[PATCH] [PATCH] clang internal library headers changes for C++ modules

[Yunzhong Gao]

The header of lib/Headers/_denormals.h says, "_denormals.h - SSE intrinsics", is it true? The header seems to only define a few macros.
The header of _gnuc_va_list.h maybe should include a one-line description too.

_gnuc_va_list.h uses "#pragma once" while the other header uses:

  #ifndef __DENORMALS_H
  #define __DENORMALS_H
  ...
  #endif
