Use GCC builtins for rint functions if desired.
This patch is using the corresponding GCC builtin for rintf, rint, rintl and rintf128 if the USE_FUNCTION_BUILTIN macros are defined to one in math-use-builtins.h. This is the case for s390 if build with at least --march=z196 --mzarch. Otherwise the generic implementation is used. The code of the generic implementation is not changed.
