tests: Add tests for the PVR

The PVR is a privileged read-only SPR. Test reading and writing in both
supervisor and problem state. In supervisor state reading returns
microwatt's assigned PVR number and writing is a noop. In problem state
both reading and writing cause privileged instruction interrupts.

tests: Add a test for privileged instruction interrupts

This adds a test that tries to execute various privileged instructions
with MSR[PR] = 1.  This also incidentally tests some of the MSR bit
manipulations.
