de4ba3b22a Minor cleanup to all the switches after MatchInstructionImpl in all the AsmParsers. 
Make sure they all have llvm_unreachable on the default path out of the switch. Remove unnecessary "default: break". Remove a 'return' after unreachable. Fix some indentation.

9127b613b1 TableGen: allow use of uint64_t for available features mask. 
ARM in particular is getting dangerously close to exceeding 32 bits worth of
possible subtarget features. When this happens, various parts of MC start to
fail inexplicably as masks get truncated to "unsigned".

Mostly just refactoring at present, and there's probably no way to test.

f670b953e7 AsmMatchers: Use unique_ptr to manage ownership of MCParsedAsmOperand 
I saw at least a memory leak or two from inspection (on probably
untested error paths) and r206991, which was the original inspiration
for this change.

I ran this idea by Jim Grosbach a few weeks ago & he was OK with it.
Since it's a basically mechanical patch that seemed sufficient - usual
post-commit review, revert, etc, as needed.

c242bd4b23 Create MCTargetOptions. 
For now it contains a single flag, SanitizeAddress, which enables
AddressSanitizer instrumentation of inline assembly.

code this looks correct, but could use review. The previous
was definitely not correct.
