Chad Rosier 45a52fa097 [ms-inline asm] Force the use of a base pointer if the MachineFunction includes
MS-style inline assembly.

This is a follow-on to r175334.  Forcing a FP to be emitted doesn't ensure it
will be used.  Therefore, force the base pointer as well.  We now treat MS
inline assembly in the same way we treat functions with dynamic stack
realignment and VLAs.  This guarantees the BP will be used to reference 
parameters and locals.

Chad Rosier 925c9b499e [ms-inline asm] Do not omit the frame pointer if we have ms-inline assembly.
If the frame pointer is omitted, and any stack changes occur in the inline
assembly, e.g.: "pusha", then any C local variable or C argument references
will be incorrect.  

I pass no judgement on anyone who would do such a thing. ;)

Chad Rosier 1bbaa449ad [ms-inline asm] Add support for the [] operator. Essentially, [expr1][expr2] is
equivalent to [expr1 + expr2].  See test cases for more examples.

Chad Rosier dd5eada241 [ms-inline asm] Add back-end test case for r166632. Make sure we emit the
correct .s output as well as get the correct encoding by the integrated
assembler.

Chad Rosier 271623f8ae [ms-inline asm] Add support in the X86AsmPrinter for printing memory references
in the Intel syntax.

The MC layer supports emitting in the Intel syntax, but this would require the
inline assembly MachineInstr to be lowered to an MCInst before emission.  This
is potential future work, but for now emitting directly from the MachineInstr
suffices.
