pytime: add _PyTime_check_mul_overflow() macro to avoid undefined behaviour Overflow test in test_FromSecondsObject() fails on FreeBSD 10.0 buildbot which uses clang. clang implements more aggressive optimization which gives different result than GCC on undefined behaviours. Check if a multiplication will overflow, instead of checking if a multiplicatin had overflowed, to avoid undefined behaviour. Add also debug information if the test on overflow fails.
