Log Message:
-----------
Remove i386 MMX detection for instrumentation (#2121)
This wouldn't compile for 32-bit Linux because 'xmmCapable' calls
'cpuidCall' which is only compiled on Windows. The Win64 version reads
off the end of 'result', so that likely never worked. At this point, I'm
quite confident that anyone rewriting Win32 binaries is likely doing so
on i386 that supports MMX. This wouldn't work on non-x86 Win32 platforms
because of the inline assembly.
