Capture JTAG bitbang log from most recent SMP debug test.
...
Regarding intermittent failure of SMP debug MemorySampleSingle test:
https://twitter.com/wren6991/status/1640153934445543426
Seems to be an OpenOCD issue, not a Hazard3 issue.

tb_cxxrtl: explicitly use set<bool> when there is only one timer IRQ

assignment to single-bit wire from the CXXRTL harness.

a861a110c1
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.
