Pull in r186696 from upstream clang trunk:

  This patch implements __get_cpuid_max() as an inline and __cpuid()
  and __cpuid_count() as macros to be compatible with GCC's cpuid.h.
  It also adds bit_<foo> constants for the various feature bits as
  described in version 039 (May 2011) of Intel's SDM Volume 2 in the
  description of the CPUID instruction.  The list of bit_<foo>
  constants is a bit exhaustive (GCC doesn't do near this many).  More
  bits could be added from a newer version of SDM if desired.

  Patch by John Baldwin!

This should fix several ports which depend on this functionality being
available.
