A little tweak to the SFINAE condition reporting. Don't say:
candidate template ignored: substitution failed [with T = int]: no type named 'type' in 'std::enable_if<false, void>'
Instead, just say:
candidate template ignored: disabled by 'enable_if' [with T = int]
... and point at the enable_if condition which (we assume) failed.
This is applied to all cases where the user writes 'typename enable_if<...>::type' (optionally prefixed with a nested name specifier), and 'enable_if<...>' names a complete class type which does not have a member named 'type', and this results in a candidate function being ignored in a SFINAE context. Thus it catches 'std::enable_if', 'std::__1::enable_if', 'boost::enable_if' and 'llvm::enable_if'.
