Since the new space is always empty after a full GC, the old-to-new
remembered set is also always empty after a full GC. This means we can
get rid of the sweeping_slot_set_.

This slot set was used to allow the main thread to insert into the
old-to-new remembered set non-atomically. The sweeping slot set was
owned by the sweeper, which deletes slots in free memory from it. The
main thread would start with an empty old-to-new remembered set. After
sweeping both slot sets are merged again.

The sweeper now needs to behave differently during a GC. When sweeping
a page during full GC, the sweeper needs to delete old-to-new-slots in
free memory.

Outside of the GC the sweeper isn't allowed to remove from the
old-to-new slots anymore. This would race with the main thread that adds
slots to that remembered set while the sweeper is running. However,
there should be no recorded slots in free memory. DCHECKing this is
tricky though, because we would need to synchronize with the main
thread right-trimming objects and at least String::MakeThin only deletes
slots after the map release-store.

The current safety margin between the JS stack limit and the actual
boundary of the stack space reserved by the simulator can be overrun by
a large frame.
Raise this margin to 4KiB, corresponding to the "large frame" threshold.
This ensures that the stack check is executed before the frame is
allocated if the frame is larger than this margin.

> [osr] Basic support for concurrent OSR
>
> This CL adds basic support behind --concurrent-osr,
> disabled by default.
>
> When enabled:
> 1) the first OSR request starts a concurrent OSR compile job.
> 2) on completion, the code object is inserted into the OSR cache.
> 3) the next OSR request picks up the cached code (assuming the request
>    came from the same JumpLoop bytecode).
>
> We add a new osr optimization marker on the feedback vector to
> track whether an OSR compile is currently in progress.
>
> One fundamental issue remains: step 3) above is not guaranteed to
> hit the same JumpLoop, and a mismatch means the OSR'd code cannot
> be installed. This will be addressed in a followup by targeting
> specific bytecode offsets for the install request.

In JSCallReducer::ReduceArrayPrototypeShift, when disable
FLAG_turbo_loop_variable, typer cannot infer loop phi variable
is in [1, kMaxCopyElements-1], and will break in representing
kRepFloat64 (Range(1, inf)) to kRepWord64 when converting
input for kLoadElement. So we need to add type guard for loop
variable. And we need to use loop phi variable when using
NumberLessThan to check terminate and updating phi loop variable,
otherwise which will break inducing variables in LoopVariableOptimizer.

As a follow-up of
https://chromium-review.googlesource.com/c/v8/v8/+/3481475,
this renames a few more operations related to property stores to keep
them consistent and adds comments to explain about what they do.

Summary of the renamed identifiers:

- SetPropertyInLiteral -> CreateDataProperty: this implements
  [[CreateDataProperty]] in the spec which does [[DefineOwnProperty]]
  instead of [[Set]], so rename for clarity.
- IsStoreIC(), IsStoreICKind() -> IsSetNamedIC(), IsSetNamedICKind():
  these only check whether the feedback kind is kSetNamedSloppy or
  kSetNamedStrict, so the scope can be narrowed.
- StoreMode::kOrdinary -> StoreMode::kSet: this implements [[Set]]
  in the spec and is used by both KeyedStoreIC and
  StoreIC to set the properties when there is no feedback.
- StoreMode::kInLiteral -> StoreMode::kDefineKeyedOwnInLiteral:
  this implements [[CreateDataProperty]] while expecting the receiver
  to be a JSObject created by us (the `InLiteral` part). Prepend
  `DefineKeyedOwn` to it so that it's more aligned with other
  StoreModes - it should be possible to just merge this into the
  more generic StoreMode::kDefineKeyedOwn later.
- KeyedStoreGenericAssembler::SetProperty ->
  KeyedStoreGenericAssembler::StoreProperty: these helpers are used by
  both define and set operations, distinguished with the StoreMode,
  so rename it to the more generic StoreProperty.

Nodes can now hold a LazyDeoptSafepoint which stores the frame state in
case they trigger a lazy deopt. OpProperties have a new CanLazyDeopt
bit, and codegen emits a safepoint table entry + lazy deopt for all
nodes with this bit. Also, we now check the deoptimized code bit on
entry into the maglev compiled function.

An example use of these lazy deopts is added as a PropertyCell fast path
for LdaGlobal, which adds a code dependency on the property cell.

This CL adds basic support behind --concurrent-osr,
disabled by default.

When enabled:
1) the first OSR request starts a concurrent OSR compile job.
2) on completion, the code object is inserted into the OSR cache.
3) the next OSR request picks up the cached code (assuming the request
   came from the same JumpLoop bytecode).

We add a new osr optimization marker on the feedback vector to
track whether an OSR compile is currently in progress.

One fundamental issue remains: step 3) above is not guaranteed to
hit the same JumpLoop, and a mismatch means the OSR'd code cannot
be installed. This will be addressed in a followup by targeting
specific bytecode offsets for the install request.

This change is based on fanchen.kong@intel.com's earlier
change crrev.com/c/3369361, thank you!
