Add two new tests for IRQs-over-Zcmp, and fix a bug they found:
...
Interrupting the PC-setting step of a cm.popret (only) can sample the return target
as the exception return PC, which will cause the stack pointer adjust to be skipped
when returning from the IRQ. Fix this by making the PC-setting step uninterruptible
(note the PC-setting step is the instruction we execute first out of the group
of instructions specified in the Zc spec as being atomic wrt interrupts. This
does not itself imply that the PC-setting step is uninterruptible, it just
requires that when the PC-setting step retires, all following steps also retire.
However this is not sufficient given the special case logic that allows the jr
ra PC-setting step to execute before the final stack adjust as an optimisation.)

Update to the latest riscv-arch-test. This uses the new test
...
framework -- scripts are a little janky for now.
Note there is one test failure (cebreak-01) -- analysis shows
this is due to the reference vector expecting mtval to be set
informatively, whereas our implementation (legally) ties it
to zero. Non-mtval-related signature for that test is correct
so I'm saying this is fine.
