Introduce __has_extension macro __has_extension is a function-like macro which takes the same set of feature identifiers as __has_feature. It evaluates to 1 if the feature is supported by Clang in the current language (either as a language extension or a standard language feature) or 0 if not. At the same time, add support for the C1X feature identifiers c_generic_selections (renamed from generic_selections) and c_static_assert, and document them. Patch by myself and Jean-Daniel Dupas. llvm-svn: 131308
