hmm can't use fu/spr/test/test_pipe_caller.py (or the compunit variant)
because for OP_MTSPR/MFSPR calling those instructions results in the
opcode being *changed* to OP_TRAP, which of course the SPR pipeline
doesn't support.

have to find a different way (global tests on the full compunit suite,
test_core.py, test_issuer.py etc.)
