Internals: Optimize temporary memory allocations (#6517) 
This patch gets rid of over 80% of temporary dynamic memory allocations
(when a malloced node is immediately freed with no other malloc in
between). It also gets rid of over 20% of all calls to malloc.

It's worth ~3% average verilation speed up with tcmalloc, and more
without tcmalloc.

CI: Add 60 minute timeout to RTLMeter compile and run steps (#6506) 
The default timeout for a job in GitHub Actions is 6 hours, which is
both too long, but more importantly, when reached the job is 'cancelled'
instead of 'failed'. Use the new `--timeout` option on `rtlmeter run`
instead to add a 60 minute timeout to compile and execute steps. (This
is ~3x longer than recent worst runs in the CI)

Improve Loop unrolling (#6480) (#6493) 
This patch implements #6480. All loop statements are represented using
AstLoop and AstLoopTest.

This necessitates rework of the loop unroller to handle loops of
arbitrary form. To enable this, I have split the old unroller used for
'generate for' statements and moved it into V3Param, and subsequently
rewrote V3Unroll to handle the new representation. V3Unroll can now
unroll more complex loops, including with loop conditions containing
multiple variable references or inlined functions.

Handling the more generic code also requires some restrictions. If a
loop contains any of the following, it cannot be unrolled:
- A timing control that might suspend the loop
- A non-inlined call to a non-pure function

These constructs can change the values of variables in the loop, so are
generally not safe to unroll if they are present. (We could still unroll
if all the variables needed for unrolling are automatic, however we
don't do that right now.)

These restrictions seem ok in the benchmark suite, where the new
unroller can generally unroll many more loops than before.
