Reid Kleckner 221f6d777e Use Clang's __has_* macros in Compiler.h to test for features ... When targetting Windows, clang does not define __GNUC__, and as a result we don't use our attributes with it. This leads to warnings about unused functions that are already annotated with LLVM_ATTRIBUTE_UNUSED. Rather than testing for __clang__, we can use its __has_attribute and __has_builtin macros directlty. While I'm here, conditionally define and use __GNUC_PREREQ for gcc version checks. Spelling the check out with three comparisons is verbose and error prone.
