Add parsing for references to member function templates with explicit
template argument lists, e.g., x.f<int>().

PR4836, part 1: add Sema support for __builtin_isnan and friends; they

Omnibus friend decl refactoring.  Instead of cloning AST classes for friend
declarations of same, introduce a single AST class and add appropriate bits
(encoded in the namespace) for whether a decl is "real" or not.  Much hackery
about previously-declared / not-previously-declared, but it's essentially
mandated by the standard that friends alter lookup, and this is at least
fairly non-intrusive.
