So far creating scripts always grew the script_list without ever
reusing cleared slots or shrinking. While this is probably not a
problem with script_list in practice, this is still a memory leak.

Fix this leak by using WeakArrayList::Append instead of AddToEnd.
Append adds to the end of the array, but potentially compacts and
shrinks the list as well. Other WeakArrayLists can use this method as
well, as long as they are not using indices into this array.

For finching Liftoff on mobile, we want to support Liftoff-only,
TurboFan-only, and Liftoff with tier-up to TurboFan. Hence, chrome needs
to be able to set the liftoff flag separately from the tier-up flag, and
there should not be an implication, since that implication would be
applied before all flags have been set to their final state.
See https://crrev.com/c/1988360 for the chromium-side change.

Note that this CL does not change any defaults.
After this change, Liftoff can be disabled by passing '--no-liftoff',
independent of the tier-up flag (this would be a TurboFan-only
configuration).
A Liftoff-only version would specify --liftoff and --no-wasm-tier-up.
The default on Desktop (--liftoff and --wasm-tier-up) compiles with
Liftoff first, and tiers up to TurboFan.

Remove the explicit script handle from ParseInfo, and make it either
a Handle that is passed around where needed, or one inferred from the
SharedFunctionInfo.

This will be useful for compilation finalization using the off-thread
factory, which will not generate real Handles since it has no access
to the Isolate.

Currently, the code does not take hint register in preference.
This CL initializes current_free according to initial reg (which maybe hint_reg),
to ensure that any candidate that equals this one won't replace hint register.

The code in TurboAssembler::LoadFromConstantsTable uses special code
to avoid clobbering the scratch register ip by giving different
argument registers to ldr. This used to be motivated by
DirectCEntryStub::GenerateCall relying on LookupConstant not clobbering
ip (see https://crrev.com/c/1070980). Now that this code is gone,
there is no more reason for preserving ip and it's fragile, so it's better
to remove this special handling.

Background threads are not supposed to use any handles, so this
handle scope is not needed.

AllocateScopeInfos should only be called for not-yet unallocated scopes,
so we can DCHECK for nullness rather than having a branch for it.

Most dead variable warnings in GCMole are false positives, either from
failing to detect that TryEvacuateObject returning false means it didn't
allocate, or a regex error thinking that GarbageCollectionReasonToString
causes garbage collection (because the mangled version is something like
GarbageCollectionReasonToString[...]GarbageCollectionReason, and that
matches /Collect.*Garbage/).

Update the whitelist and fix the "Collect.*Garbage" regex to only look
at the function name.
