[PATCH][testsuite]: Fix testism in avx512fp16-xorsign-1.c

[Tamar Christina]

After r16-7762-g0383e6c398a this test now only vectorizes
the main loop and not the early break result checking loop
due to the FP * being able to raise an FE and we're compiling
with -ftrapping-math.

Test was marked unsupported so didn't notice it before.

Tested in x86_64-pc-linux-gnu and no issues.

Pushed to master.

Thanks,
Tamar
