For stack-switching, we create a callable object from the
WasmResume builtin and pass that as the onFulfilled argument
of Promise#then. We don't need to create this callable object each time
we suspend. Instead, create it when we initialize the Suspender object
and store it there.

This is a reland of commit 1f0d7d20

The fix merges concurrent marking tasks when marking in the atomic
pause. Without the fix, Oilpan markers would continue running
concurrently, possibly discovering new V8 objects. This violates the
assumption that the final transitive closure runs on a single thread.

Original change's description:
> cppgc-js: Concurrently process v8::TracedReference
>
> Adds concurrent marking for reaching through v8::TracedReference.
> Before this CL, a v8::TracedReference would always be processed on the
> main thread by pushing a callback for each encountered reference.
>
> This CL now wires up concurrent handling for such references. In particular:
> - Global handles are already marked as well and not repurposed during
>   the same GC cycle.
> - Since global handles are not repurposed, it is enough to
>   double-deref to the V8 object, checking for possible null pointers.
> - The bitmap for global handle flags is mostly non-atomic, with the
>   markbit being the exception.
> - Finally, all state is wired up in CppHeap. Concurrent markers keep
>   their own local worklist while the mutator marker directly pushes to
>   the worklist owned by V8.

This particular branch in CompileOptimizedOSR relies on a precise
invocation count at counts 0 and 1. The invocation count is unreliable
not only in the previously described situation (--always-opt), but also
e.g. when forcing optimization on the first execution through other
means like %OptimizeFunctionOnNextCall. Let's simply rewrite the
condition to explicitly exclude kIsInProgress.

This is a reland of commit 51b99213

Fixed in reland:
- bytecode_age was incorrectly still accessed as an int8 (instead
  of int16).
- age and osr state were incorrectly reset on ia32 (16-bit write
  instead of 32-bit).

Original change's description:

>
> .. for concurrent OSR. There, the challenge is to hit the correct
> JumpLoop bytecode once compilation completes, since execution has
> moved on in the meantime.

>   bytecode_age: uint16;  // Only 3 bits used.
>   // [...]
>
> Note urgency and install target are packed into one 16 bit field,
> we can thus merge both checks into one comparison within JumpLoop.
> Note also that these fields are adjacent to the bytecode age; we
> still reset both OSR state and age with a single (now 32-bit)
> store.
>
> The install target is the lowest 13 bits of the bytecode offset.
> When set, every reached JumpLoop will check `is this my offset?`,

into a single non-private class that can be inherited to override

- Parse the condensed source position info support for jitted code
- Add progress bar/circle to loader
- Use temporary Array instead of concatenated strings in escapeField to
  reduce gc pressure
- Use bound functions as event handlers in more places
- Various timeline legend fixes:
  - Fix columns alignment when duration is present
  - Use fixed width to avoid breaking the UI
  - Correctly show total/percents for 'All' and 'Selection' entries
  - Improve usability of filtering buttons: added tooltips and fixed
    redrawing on filtering

The tier up check in br_if is only executed conditionally, so it is
not allowed to update any cache state. Later code would work with that
updated state, even though the corresponding code would not have
executed.
There was a partial implementation for this by passing in a scratch
register for {TierupCheck}, but {TierupCheckOnExit} has the same
problem, and needs up to three scratch registers.

Until we come up with a better solution, just snapshot the cache state
before doing the tier up check, and restore it later. This has some
performance cost, but it's an effective fix.

This is a reland of commit c482a66b

Original change's description:
> Enable PAC and BTI for runtime generated code.
>
> This patch enables PAC and BTI for runtime generated code when PAC
> is enabled. Additional BTI landing pads will resolve to NOOP when
> running on non BTI device and will not cause functional problems.

Opportunistically specializing the inlined function's signature
based on statically available type information in the caller is
currently important for performance, but can make inlining fail
if parts of the inlinee relied on the more generic types.
This patch addresses that problem by retrying with the original
signature in such cases.
Long-term, check elimination should be based on typed IR nodes
instead.
