Make sure the SPRs are initialized and we can't read X state.

This tests that floating-point unavailable exceptions occur as expected
on FP loads and stores, and that the simple FP loads and stores appear
to give reasonable results.

This checks that the instructions seem to update memory as expected,
and also that they generate alignment interrupts when necessary.
We don't check whether the memory update is atomic as we don't have
SMP yet.

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.

This adds tests to check that the MMU and dTLB are translating
addresses and checking permissions correctly.
We use a simple 2-level radix tree. The radix tree maps 2GB of
address space and has a 1024-entry page directory pointing to
512-entry page table pages.

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.

Checks interrupt masking and priorities.
Adds to `make test_xics` which is run in `make check` also.

This adds test cases for:
- sc, illegals and decrementer exceptions
- decrementer overflow
- rfid
- mt/mf sprg0/1 srr0/1
- mtdec
- mtmsrd
- sc
It also adds these test cases to make check/check_light
