[KERNEL32_APITEST] Enable SSE for TestSSEExceptions. CORE-17202

Clang will not let us use SSE intrinsics at all when compiling for a
target that doesn't support SSE. Since this test is a special case,
we can simply fix this by changing the options for one function.
The alternative would be to use our own inline functions for the
intrinsics instead of the builtins, like we do for GCC.
