Craig Topper 589ceee7f4 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.

Tim Northover 26bb14e6a7 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.

David Blaikie 960ea3f018 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.

Craig Topper b0c941bebd [C++11] Add 'override' keywords and remove 'virtual'. Additionally add 'final' and leave 'virtual' on some methods that are marked virtual without overriding anything and have no obvious overrides themselves. Sparc edition

Evgeniy Stepanov 0a951b775e Create MCTargetOptions. 
For now it contains a single flag, SanitizeAddress, which enables
AddressSanitizer instrumentation of inline assembly.
