[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] These should be int64_t, not uint64_t.

Two small cleanups for ELF's templates.

* We only ever specialize these templates with an instantiation of ELFType,
  so we don't need a template template.
* Replace LLVM_ELF_COMMA with just passing the individual parameters to the
  macro. This requires a second macro for when we only have ELFT, but that
  is still a small win.
