Correct, I found it while investigating major regressions in a few benchmarks.

Note I see the long, long long, int128, float, double, long double overloads,
but where is the plain int overload defined? 

I bet that adding an int overload that redirects to __builtin_abs similar to
the others will fix the issue.
