Fix FXC compile errors on modulo by zero

Just like for divide, FXC fails with the exact same error when
performing a modulo on a value that FXC determines to be zero. We
address it in the same way as we do for divide.

This also fixes a couple of the vk-gl-cts tests for which I manually
generated expectation files for.
