#12193: Reintroduce GC compaction for shared pools.
Adds a parallel compactor for the shared pools (which contain major heap
blocks sized less than 128 words). Explicit only for now, on calls to
Gc.compact.

-
#12850: Update Gc.quick_stat data at the end of major cycles and compaction.
This PR adds an additional caml_collect_gc_stats_sample_stw to the major heap
cycling STW. This means that Gc.quick_stat now actually reflects the state of
the heap after a major cycle or compaction.

further bugs with the Multicore systhreads implementation.

Multicore: soundness, liveness, and performance issues.
Do not crash if a signal handler is called from an unregistered C

#12236, #12386, #12391, #12496, #12673: Use syntax as sole determiner of arity.
This changes function arity to be based solely on the source program's
parsetree. Previously, the heuristic for arity had more subtle heuristics
that involved type information about patterns. Function arity is important
because it determines when a pattern match's effects run and is an input
into the fast path for function application.
This change affects tooling; it changes the function constructs in parsetree
and typedtree.
