objc_gc wants a pointer type, not a function type; give it a more appropriate diagnostic. Also, these attributes are commonly written with macros which we actually pre-define, so instead of expanding the macro location, refer to the instantiation location and name it using the macro loc. llvm-svn: 127219

Pretty up the wrong-number-of-arguments-for-attribute diagnostic by using a custom plural form. Split out the range diagnostics as their own message. llvm-svn: 126840
