Code Object V2 has been deprecated for more than a year now. We can
safely remove it from LLVM.

- [clang] Remove support for the `-mcode-object-version=2` option.
- [lld] Remove/refactor tests that were still using COV2
- [llvm] Update AMDGPUUsage.rst
- Code Object V2 docs are left for informational purposes because those
code objects may still be supported by the runtime/loaders for a while.
- [AMDGPU] Remove COV2 emission capabilities.
- [AMDGPU] Remove `MetadataStreamerYamlV2` which was only used by COV2
- [AMDGPU] Update all tests that were still using COV2 - They are either
deleted or ported directly to code object v4 (as v3 is also planned to
be removed soon).
Now that VPInstruction can manage fast math flags via
VPRecipeWithIRFlags, use them directly to model the fast-math flags of
the select created for the final reduction value instead of adding them
late.
One big issue with DirectXShaderCompiler was test coverage: DXIL and
SPIR-V backends had their own tests. When a bug was found in one, the
other wasn't always checked. This lead to unequal support of HLSL for
both backends. We'd like to avoid those issues here, hence the
test-sharing.

By default, all the tests in this folder are marked as requiring
DirectX. But as SPIR-V support grows, each test drop this requirement,
and check the SPIR-V behavior.

I would have preferred to mark new tests as XFAIL for SPIR-V by default,
so we could differentiate real unsupported tests (as SPIR-V has no
equivalent), from newly added tests. But the way LIT is built, I don't
think this is possible.

TestWatchTaggedAddress.py: Updated the expected watchpoint types,
though I'm not sure there should be a differnt default for the two
ways of setting them, that needs to be confirmed.

TestStepOverWatchpoint.py: Skipped this everywhere because I think
what used to happen is you couldn't put 2 watchpoints on the same
address (after alignment). I guess that this is now allowed because
modify watchpoints aren't accounted for, but likely should be.

This adds the ability to read streaming SVE registers,
ZA, SVCR and SVG from core files.

Streaming SVE is in a new note NT_ARM_SSVE but otherwise
has the same format as SVE. So I've done the same as I
did for live processes and reused the existing SVE state
with an extra state for the mode variable.

ZA is in a note NT_ARM_ZA and again the handling matches
live processes. Except that it gets setup only once. A
disabled ZA reads as 0s as usual.

SVCR and SVG are pseudo registers, generated from the notes.

An important detail is that the notes represent what
you would have got if you read from ptrace at the time of
the crash.

This means that for a corefile in non-streaming mode,
there is still an NT_ARM_SSVE note and we check the header
flags to tell if it is active. We cannot just say if you
have the note you're in streaming mode.

The kernel does not provide register values for the inactive
mode and even if it did, they would be undefined, so if we find
streaming state, we ignore the non-streaming state.

Same for ZA, a disabled ZA still has the header in the note.

The tests do not cover all combinations but enough different
vector lengths, modes and ZA states to be confident.

Old iterator is invalidated upon SmallVector elements additions. Stores
index instead of iterator to avoid this.

Fixes llvm#66938

PR: llvm#66954
Derived-type-spec (such as `type(t)`) typically cause the instantiation
of a class which is also used to define the offsets of its data
components and the size of the class.

Fortran derived types are always "completely" defined (i.e., no
incomplete / opaque derived types exist on which we can build a pointer
to them like in C/C++) so they can have their offsets always computed.

However, we must be careful not to instantiate a derived type while it
is being defined. This can happen due to cycles introduced by forward
references, such as the one below.

```lang=fortran
  type t1
    type(t2), pointer :: b ! (A)
  end type t1

  type :: t2 ! (B)
    type(t1), pointer :: a ! (C)
  end type t2 ! (D)
```

At `(A)`, flang determines that this is a forward declaration so no
instantiation happens.

At `(B)`, flang determines `t2` is not a forward declaration anymore,
because we are defining it.

At `(C)`, flang chooses to instantiate `t1`. Instantiation of `t1` finds
the field `b` at `(A)`. Now `t2` is not a forward declaration anymore,
so it can be instantiated. But at this point the field `a` has not been
added to `t2`, so we compute the size of an empty class. Because this
computation is done just once, we end emitting a wrong derived type
descriptor with a `sizeinbytes` field set to 0.

Because these kind of cycles can only happen via forward referenced
derived types specifiers, the idea here is to avoid instantiating the
derived type being defined (i.e. `t2`) until `(D)`. Keeping the
attribute "is forward reference" set until `(D)` avoids that.

…lvm#65997)

Similar to llvm#65598, if we're using a vslideup to insert a fixed length
vector into another vector, then we can work out the minimum number of
registers it will need to slide up across given the minimum VLEN, and
shrink the type operated on to reduce LMUL accordingly.

This is somewhat dependent on llvm#66211 , since it introduces a subregister
copy that triggers a crash with -early-live-intervals in one of the
tests.

…ctorize_children_and...}. (llvm#66575)

This PR renames the vectorization transform ops as follows:

* `structured.masked_vectorize` => `structured.vectorize`. This reflects
the fact that since [recently](https://reviews.llvm.org/D157774) the op
can also handle the unmasked case.
* `structured.vectorize` =>
`structured.vectorize_children_and_applies_patterns`. This reflects the
fact that the op does not just vectorize the given payload op but all
vectorizable children contained in it, and applies patterns before and
after for preparation and clean-up.

This rename was discussed first
[here](https://reviews.llvm.org/D157774).

The PR also adapts and cleans ups the tablegen description of the
`VectorizeChildrenAndApplyPatternsOp` (formerly `VectorizeOp`).

Header phi recipes have the start value (incoming from outside the loop)

This implements the [[msvc::no_unique_address]] attribute.

b1e3cd1 dropped the leading slash here,
presumably unintentionally.

(I don't understand Driver well enough to know how/where this is
supposed
to be tested, but it broke clangd on any project that uses the
system-installed -stdlib=libc++ on a standard debian install)
This problem was accidentally discovered by the internal symbolizer, but
it's relevant for external one as well, see the test.

If we just disable tagging, there may still be tagged allocations that
have already been freed. After disabling tagging, these tagged
allocations can be released to the user as-is, which would later break
the "invalid-free" check.

We cannot just disable the "invalid-free" check with disabled tagging,
because if we re-enable tagging, the issue still applies to allocations
created when it was disabled.

The fix is to continue tagging with zero even if tagging is disabled.

This makes the "disabled" mode less efficient, but this is not the
primary use case.

These are not supported by the backend.

The comment that got deleted was out of place, and it exists in the call

I'd guarded this case in D158874 to avoid regressions, and decided to go investigate what was going on. The solution turns out to be a generic splat matching extension to handle INSERT_SUBVECTOR. In theory, we could see these from other sources as well, but for some reason we only seem to see the i64 extract on rv32 case in practice. Not sure why that is to be honest.

Introduces a bug in the `TosaInferShapesPass` when an operand type was
already inferred.

interprets the `ValueShapeRange` as a normal `ValueRange` and looses the
information of the inference.

This PR changes the logic of the shape inference a bit. Instead of
saving the type information in a `DenseMap` and updating the types after
the whole analysis for a region, it now updates the types directly in
each iteration. That way the operands always have the inferred type.

While looking into reducing needless interdependencies between upstream
MLIR dialects and passes, I discovered that the ROCDL Dialect
redundantely uses links in `VectorToLLVM` conversion pass when it
actually requires just the LLVM Dialect. Furthermore, after a build
failure, I ran `ninja -t missingdeps` which revealed that the NVVM
Dialect depends on headers of the GPU dialect
(https://github.com/llvm/llvm-project/blob/211c9752c8200fbb3ff7be1f6aa98037901758ce/mlir/include/mlir/Dialect/LLVMIR/NVVMDialect.h#L18)
without stating so in CMake.
This causes flaky builds as it is not guaranteed that the header exists
prior to the dialect being compiled.

Note the new surface syntax allows for defining a dimToLvl and lvlToDim
map at once (where usually the latter can be inferred from the former,
but not always). This revision adds storage for the latter, together
with some intial boilerplate. The actual support (inference, validation,
printing, etc.) is still TBD of course.

…tePluginObject

After llvm#68052 this function changed from returning
a nullptr with `return {};` to returning Expected and hitting `llvm_unreachable` before it could
do so.

I gather that we're never supposed to call this function, but on Windows we actually do call
this function because `interpreter->CreateScriptedProcessInterface()` returns
`ScriptedProcessInterface` not `ScriptedProcessPythonInterface`. Likely because
`target_sp->GetDebugger().GetScriptInterpreter()` also does not return a Python related class.

That might be a bug on the Windows side, or an artifact of how our build is setup,
but whatever it is, having `CreatePluginObject` return an error and
the caller check it, fixes the failing test.
