Rémi Verschelde 2cf6ac6c50 Replace FALLTHROUGH macro by C++17 [[fallthrough]] 
This attribute is now part of the standard we target so we no longer
need compiler-specific hacks.

Also enables -Wimplicit-fallthrough for Clang now that we can properly
support it. It's already on by default for GCC's -Wextra.

Fixes new warnings raised by Clang's -Wimplicit-fallthrough.
