049ffbbdf2 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.

c50f986b4d 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.

d6af41b2eb Create MCTargetOptions. 
For now it contains a single flag, SanitizeAddress, which enables
AddressSanitizer instrumentation of inline assembly.

22221ee0e3 Fix out of bounds access to the double regs array. Given the 
code this looks correct, but could use review. The previous
was definitely not correct.
