Paul Mackerras 29fabeb12e tests/misc: Add a test for correct CTR and LR updating by branches 
This adds a test with a bdnzl followed immediately by a bdnz, to check
that CTR and LR both get evaluated and written back correctly in this
situation.

Jordan Niethe 737ebd92f5 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.

Shawn Anastasio 8b161c6dc6 Add a new misc test suite with addpcis tests 
The two tests obtain NIA with bl+mflr+addi and then compare it
against addpcis with the minimum and maximum immediate operand values.

They were also tested on a real POWER9 system (in userspace) for good
measure.
