testsuite/x86: Add -mfpmath=sse to add_options_for_float16

Add -mfpmath=sse to add_options_for_float16 to avoid error:
'-fexcess-precision=16' is not compatible with '-mfpmath=387'
when compiling gcc.dg/tree-ssa/pow_fold_1.c.

gcc/testsuite/ChangeLog:

	* lib/target-supports.exp (add_options_for_float16): Add -mpfpmath=sse.
