  Changed paths:
    M llvm/include/llvm/Support/X86TargetParser.def
    M llvm/lib/Support/Host.cpp
    M llvm/lib/Support/X86TargetParser.cpp

  Log Message:
  -----------
  Revert 51b0da73 "Recommit "[X86] Merge the FEATURE_64BIT and FEATURE_EM64T bits in X86TargetParser.def.""

It gets miscompiled with GCC 5.3, causing Clang to crash with
"error: unknown target CPU 'x86-64'"

See the llvm-commits thread for reproduction steps.

This reverts commit 51b0da731af75c68dd521e04cc576d5a611b1612.
