Chad Rosier 738ea2590f [ms-inline asm] Add a new function, GetMCInstOperandNum, to the 
AsmMatcherEmitter.  This function maps inline assembly operands to MCInst
operands.

For example, '__asm mov j, eax' is represented by the follow MCInst:

<MCInst 1460 <MCOperand Reg:0> <MCOperand Imm:1> <MCOperand Reg:0> 
             <MCOperand Expr:(j)> <MCOperand Reg:0> <MCOperand Reg:43>>

The first 5 MCInst operands are a result of j matching as a memory operand
consisting of a BaseReg (Reg:0), MemScale (Imm:1), MemIndexReg(Reg:0), 
Expr (Expr:(j), and a MemSegReg (Reg:0).  The 6th MCInst operand represents
the eax register (Reg:43).

This translation is necessary to determine the Input and Output Exprs.  If a
single asm operand maps to multiple MCInst operands, the index of the first
MCInst operand is returned.  Ideally, it would return the operand we really
care out (i.e., the Expr:(j) in this case), but I haven't found an easy way
of doing this yet.
