Disable __has_cpp_attribute when not compiling in C++ mode. As this feature test macro only supports C++ style attributes, it doesn't apply to code compiled as C code, and can lead to diagnostics when given a scoped attribute.
This addresses PR23435.

Modify __has_attribute so that it only looks for GNU-style attributes. Removes the ability to look for generic attributes and keywords via this macro, which has the potential to be a breaking change. However, since there is __has_cpp_attribute and __has_declspec_attribute, and given the limited usefulness of querying a generic attribute name regardless of syntax, this seems like the correct path forward.

__has_attribute now understands target-specific attributes. So when you ask whether an ARM target has the "interrupt" attribute, it will return true for ARM and MSP430 targets, and false for others.

Generalize hack allowing 'const' in __has_attribute (etc) to allow any token
with identifier info. This covers most identifier-like entities (other than
the ISO646 keywords).
