[ms-inline asm] Add support for the minus unary operator. Previously, we were
...
unable to handle cases such as __asm mov eax, 8*-8.
This patch also attempts to simplify the state machine. Further, the error
reporting has been improved. Test cases included, but more will be added to
the clang side shortly.

[ms-inline asm] Add support for numeric displacement expressions in bracketed
...
memory operands.
Essentially, this layers an infix calculator on top of the parsing state
machine. The scale on the index register is still expected to be an immediate
__asm mov eax, [eax + ebx*4]
and will not work with more complex expressions. For example,
__asm mov eax, [eax + ebx*(2*2)]
The plus and minus binary operators assume the numeric value of a register is
zero so as to not change the displacement. Register operands should never
be an operand for a multiply or divide operation; the scale*indexreg
expression is always replaced with a zero on the operand stack to prevent
such a case.
