Chad Rosier 060c0ea89a [ms-inline asm] Compute the token range for each instruction within the asm.
Eventually, we'll need a way of mapping tokens (and their IdentifierInfo*) to
the operands computed by buildMSAsmPieces().

Chad Rosier d997bd1422 [ms-inline asm] Start sending non-simple inline asms to the AsmParser.
The parser still can't handle all cases, so fall back to emitting a simple
MSAsmStmt if we get into trouble.

Chad Rosier bbdd467895 [ms-inline asm] Remove the patchMSAsmStrings function. After some discussion
between Bob, Jim, Eric and I, we've decided to take a slightly different
approach.

Chad Rosier b958037958 [ms-inline asm] Have buildMSAsmString build a vector of unmodified AsmStrings.
Add a new static function, buildMSAsmPieces, that will break these strings down
into mnemonic and operands.  Upon a match failure, the idea is to use the
ErrorInfo from MatchInstructionImpl to inspect the mnemonic/operand and 
decide a course of action.  Unfortunately, there's no easy way to test this at
the moment.

Chad Rosier 5111f8650d [ms-inline asm] Do not report a Parser error when matching inline assembly.

Chad Rosier 19160b6e39 [ms-inline asm] Expose the ErrorInfo from the MatchInstructionImpl. In general,
this is the index of the operand that failed to match.

Chad Rosier 0731affaca [ms-inline asm] Extract AsmStmt handling into a separate file, so as to not
pollute SemaStmt with extraneous asm handling logic.
