Build pre-coroutine-transform coroutine body

(cherry picked from commit 0ba7d19)
@tmiasko @cuviper
Fix coroutine validation for mixed panic strategy
ae0b24f 
Validation introduced in rust-lang#113124 allows UnwindAction::Continue and
TerminatorKind::Resume to occur only in functions with ABI that can
unwind. The function ABI depends on the panic strategy, which can vary
across crates.

Usually MIR is built and validated in the same crate. The coroutine drop
glue thus far was an exception. As a result validation could fail when
mixing different panic strategies.

Avoid the problem by executing AbortUnwindingCalls along with the
validation.

(cherry picked from commit 5161b22)

Precommit test for rust-lang#118328.

Rename and add another test

(cherry picked from commit 6e956c0)
@wesleywiser @cuviper
Dispose llvm::TargetMachines prior to llvm::Context being disposed
76e6681 
If the TargetMachine is disposed after the Context is disposed, it can
lead to use after frees in some cases.

I've observed this happening occasionally on code compiled for
aarch64-pc-windows-msvc using `-Zstack-protector=strong` but other users
have reported AVs from host aarch64-pc-windows-msvc compilers as well.
