Add a FALL_THROUGH macro to compiler.h

Browse source 
Older gcc's don't support `__attribute__ ((fallthrough))`
(see https://sourceforge.net/u/begasus/tuxpaint/ci/e5c3cdfcf5e16a9b0fc3e7766bfea1d9c326b3ae/
"Haiku Fixes" by Luc), so adding a new macro to compiler.h
that is defined as "((void)0)" on older compilers.
