Allow -b flag without nosv.can_breakdown
...
As we now have OpenMP and nOS-V models for breakdown, we may have the
situation in which nOS-V traces don't have enough events to enable the
breakdown model, but we do on OpenMP. Rather than stopping, disable the
nOS-V model with a warning and continue.

Update nOS-V commit to reduce yield events

c847ec19ad
Add noisy yield test in nOS-V
...
Ensure we can call nosv_yield in a loop without generating a lot of
events when using the level 3 instrumentation level. Noisy events are
now moved to level 4, so they shouldn't appear on the trace.
Additionally, make sure that the noisy events appear on level 4.

Add nOS-V non-blocking scheduler server events
...
The events are emitted when we enter the scheduler with the non-blocking
flag, which is usually the case when using the nosv_yield and
nosv_schedpoint API functions.

Fix cast from pointer to integer in armv7
...
A pointer may not fit in a off_t type, so we first cast it to intptr_t
which must be able to hold it, then compute the diff which should fit in
a off_t and perform the cast.

Use fixed clock for sort-into-previous-region test
...
With large values of clocks, awk starts to lose precision due handling
the time as floating point values, which causes the test to fail. By
always setting the clock of the events to a known value we can just
compare the outcome as-is, without performing any arithmetic operation.
