  Log Message:
  -----------
  [X86] Fix some signedness errors in x86 headers

Another step toward enabling full -Wsystem-headers testing across all x86 headers

Fix a number of cases where the arg / return value signedness doesn't match the C/C++ intrinsic.

So far I've just added explicit casts as necessary, but we might want to address some of the mismatches directly
