- made the runner name explicit (ubuntu-22.04 instead of ubuntu-latest)
- use checkout action v3 (not v2) - silences a Github warning
- attempted to cache dependencies
- reordered the actions a bit so that the cached items are handled first
- installed all dependencies to /opt/riscv so that they can be cached more easily as a bulk

Choosing to grab the latest version of each component. I'd rather deal
with the rare failure that causes, than realize that we've been testing
against really old stuff.

* Add command "exec_progbuf"
Command "exec_progbuf" allows to execute a user-specified sequence
of instructions using the program buffer.

Because riscv_program_exec() tries to add an instruction every time
through.
This would cause an error accessing vector registers where VL > 14(?).

This should make vector accesses work on 64-bit harts that implement
Zve32*. There doesn't appear to be any way to easily determine what vsew
values are allowed, so try and notice the failure.

OpenOCD currently uses improper "fence" instruction:
"FENCE" opcode with empty predecessor and successor sets.
Such instruction has no effect and is reserved for future use
as a HINT instruction (RISC-V Unprivileged ISA spec V20191213,
section 2.9).
This patch fixes it by using the proper "fence rw,rw"
instruction.

This command is supposed to be a start at a compliance test for system
bus access. It doesn't pass against spike because it doesn't handle all
cases where the interface might be busy. It's not documented. As far as
I know nobody uses it.
So delete 400 lines of code instead of trying to fix it.

This lets the user set an itrigger trigger, which doesn't fit in the
normal breakpoint abstraction.
This implementation only allows control of a single itrigger. Hardware
could support more than one, and that may be useful to catch different
interrupts in different execution modes. But it would make the code/UI
more complex and it feels like an unlikely use case.

Then also set it when we resume in examine(), which doesn't use the full
abstractions because not all required data structures are filled out
yet.
Hopefully fixes#749.

Exit the loop when no harts are running, instead of when at least one
hart has halted.

It used to set all states to halted, but that's not right for harts that
are now unavailable. (It might be possible to call poll() at the right
time instead of duplicating some of its code, but I didn't see an easy
way to do that. The real requirement is that target->state is set to
TARGET_UNAVAILABLE before TARGET_EVENT_HALTED is is sent in
halt_finish(), because that's what triggers hwthread_update_threads(),
which must know about unavailable harts so they can be hidden from gdb.

When SMP is enabled, gdb will always use the first target in the SMP
group. That doesn't work when that first target is unavailable, but
others in the SMP group are still available.
For cases where gdb expects an operation to affect the entire group (run
control, memory access), find the first available target in an SMP group
and use that.
