Chad Rosier 65a8e0b69f [ms-inline asm] Have patchMSAsmStrings() return a vector or AsmStrings. 
The AsmParser expects a single asm instruction, but valid ms-style inline asm
statements may contain  multiple instructions.

This happens with asm blocks

__asm {
  mov ebx, eax
  mov ecx, ebx
}

or when multiple asm statements are adjacent to one another

__asm mov ebx, eax
__asm mov ecx, ebx

and

__asm mov ebx, eax __asm mov ecx, ebx

Currently, asm blocks are not properly handled.

Chad Rosier 360e1763d5 [ms-inline asm] Add basic codegen support for simple asm stmts. Currently, 
only machine specific clobbers are modeled.

Chad Rosier 83916498b8 [ms-inline asm] Add a very simple test case. Basically, we're only testing for 
crashers at the moment (and coincidentally this case was causing a crash).
