tb_cxxrtl: explicitly use set<bool> when there is only one timer IRQ
...
(i.e. single-core testbench). Avoids some odd behaviour with wide
assignment to single-bit wire from the CXXRTL harness.

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.

Remove FIXME about considering concurrent load/store and debug entry
...
in calculating the privilege of load/stores. This is safe because it
is only the *current* debug mode state which affects load/stores,
and some new properties have been added to ensure load/stores can
not be in aphase at the point debug mode is entered/exited (which
is achieved by delaying the trap). Therefore there is no way for
debug entry to inadvertently boost the privilege of an executing
U-mode load/store.
Also rename a confusingly-named signal for an unsquashable bus
transfer in stage 2 that delays IRQ entry.
