Backports a single commit to Pkg (JuliaLang/Pkg.jl#3696) which caused Pkg parallel precompile to sometimes recompile packages that were already compiled.

# Conflicts: # VERSION
As that PR is not in 1.9.
In `jl_print_task_backtraces()`. Follow-on to JuliaLang#51430.
* Emit safepoints at function entry * Make safepoint emission on function entry a codegen feature * Hoist signal page lookup outside fence * Update src/cgutils.cpp * Fix rebase
Extend the fix for JuliaLang#43578 (2939272) to cover the deadlock bug present internally in dyld4 inside the function we use to avoid the previous deadlock issue. Fix JuliaLang#49733
Accidentally missed in JuliaLang#49740 Fixes JuliaLang#49773
Presence is controlled by a build-time option. Start a separate thread which simply sleeps. When heartbeats are enabled, this thread wakes up at specified intervals to verify that user code is heartbeating as requested and if not, prints task backtraces. Also fixes the call to `maxthreadid` in `generate_precompile.jl`.

…106) Otherwise we may just observe `gc_n_threads = 0` (`jl_gc_collect` sets it to 0 in the very end of its body) and this function becomes a no-op.
When enabling heartbeats, the user must specify: - heartbeat_s: jl_heartbeat() must be called at least once every heartbeat_s; if it isn't, a one-line heartbeat loss report is printed - show_tasks_after_n: after these many heartbeat_s have passed without jl_heartbeat() being called, print task backtraces and stop all reporting - reset_after_n: after these many heartbeat_s have passed with jl_heartbeat() being called, print a heartbeats recovered message and reset reporting
…uliaLang#52164) (#112) One of the limitations is that it's only accurate right after the GC. Still might be helpful for observability purposes.
…111) We're suffering from heavy fragmentation in some of our workloads. Add a build-time option to enable 4k pages (instead of 16k) in the GC, since that improves memory utilization considerably for us. Drawback is that this may increase the number of `madvise` system calls in the sweeping phase by a factor of 4, but concurrent page sweeping should help with some of that.
Also initialize it later, outside option parsing, so that modifying jl_options before calling jl_init works. Co-authored-by: Jeff Bezanson <[email protected]>

Without this change, the compiler fails to notice that `env_threads isa Int` in the fall-through case, leading to a union-split with a branch that is in fact unreachable: ``` 43 ┄ %109 = φ (#41 => %105, #42 => %108)::Union{Nothing, Int64} │ %110 = (%109 isa Int64)::Bool └─── goto #45 if not %110 ... 45 ─ %126 = π (%109, Nothing) │ Base.convert(Int64, %126)::Union{} └─── unreachable ``` After this change, the union-split is eliminated.
