Nick Desaulniers 6a4e66854a compiler.h: drop fallback overflow checkers ...

[ Upstream commit 4eb6bd55cf ]

Once upgrading the minimum supported version of GCC to 5.1, we can drop
the fallback code for !COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW.

This is effectively a revert of commit f0907827a8 ("compiler.h: enable
builtin overflow checkers and add fallback code")
