Currently, tests for huge arguments for Sin/Cos/SinCos/Tan are disabled for s390x because the respective assembly routines don't reduce input arguments accurately enough.

The assembly routines are fixed; or better, the pure Go code should be used instead if there's no significant performance difference.

See also #29221 for more details.
