Sorry. I overlooked your comment.
This change is not related to LLVM.
Added missing files. It should now build.

Can this be merged? It'd be nice to have SuperH disassembly support in Capstone. Rizin has it's own makeshift disassembler, but it'd be nice for us to use this one, since we already use Capstone for disassembling other architectures.

[aquynh]

sorry for delay, i will have a quick review this week.

[DMaroo]

Any updates on this? @aquynh

[kabeor]
