What's the first version of clang with support for __builtin_*_overflow?
Because with your patch as is (Checking only __clang__), it's very
likely old clang builds could be broken. We have things like Clang 3 on
FATE right now.

Also, does clang-cl define __clang__ and these builtins? Because maybe
we could remove that check and just keep the GCC + Intel one. The former
should in theory cover Clang builds that are reportedly compatible with
GCC >= 5.1
