Hi All,

I'm doing AST based analysis of some code that uses MS style inline asm
(target: i686-pc-win32) and I'm seeing some new errors since the
recent(ish) changes to inline parsing:

prefetchnta 64[ESI]

   - unexpected token in argument list

prefetchnta [esi + (200*64)]

   - unexpected token in argument list

movq mm1,  0[ESI]


   unexpected token in argument list

and ecx, 111b


   invalid reference to undefined symbol

add ecx, offset $label_name

   - Asserts in
   X86AsmParser::ParseIntelOffsetOfOperator() with "Expected an identifier"

Should these cases be supported in the first place?

- Will.
