Remove use of denorm in mad fp16 test because we can't specify denorm preserve across compilers (#652)

Remove use of denorm values in this test because although using '-denorm
preserve' for DXC makes this test pass on the machines it is failing on,
there is currently no option in the clang compiler. So, the test would
still need to be xfailed for the clang compiler.

Closes #562
