On PowerPC we cannot manipulate FPSCR[VX]--it's a summary of all
the invalid exception bits, as described in Section 3.3.6.1.1 of
PowerPC Architecture Programming Environments Manual.
A proper way to cause an invalid operation exception is to set
FPSCR[VXSOFT]. Similarly, we clear all the FPSCR[VX*] bits otherwise.
