Determine if there's a getDecl member function using less hacks

Authored by aaron.ballman on Feb 24 2016, 10:29 AM.



ASTMatchersInternal uses a custom type trait to determine the presence or absence of a getDecl member function. While the current implementation works, it requires compiler-specific hackery to work around some MSVC issues. This patch replaces the original implementation with one that requires less compiler-specific work.

I assume you checked that the new trait works on MSVC.
Aren't both the same type of expression SFINAE? Is somehow one supported but not the other?
