Switch tests in test/Headers to use %clang_cc1 rather than %clang. There is no need to go through the driver indirection here, and it clutters things up as dependencies can sneak in for specific things the driver is doing. llvm-svn: 191107

Make sure we define wchar_t related macros correctly in -fms-extensions mode. This adds a test to make sure we define _WCHAR_T_DEFINED and _NATIVE_WCHAR_T_DEFINED correctly in the preprocessor, and updates stddef.h to set it when typedeffing wchar_t. llvm-svn: 180918
