compiler.h: drop fallback overflow checkers
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 f0907827a8a9 ("compiler.h: enable
builtin overflow checkers and add fallback code")
