Adapt to the C++ SIC introduced by P0021: noexcept overloading

C++17 adopts P0021R1[1], which makes noexcept be part of the function
pointer's type and thus be overloadable. It contains some provisions for
allowing a noexcept function pointer to cast implicitly to a non-
noexcept function pointer, but that fails in the presence of templates
and additional overloads that could match the type in question.

Fortunately, the paper proposed a test macro, so we can change our
sources now and be compatible with both C++14 and C++17 rules.

This first failed with Clang 4.0 trunk. This source incompatibility is
not our fault, it's the language's doing.
