Before this CL a byte was used per bucket to store whether the bucket
is possibly empty or not. This CL changes this such that each bucket
only needs a single bit.
PossiblyEmptyBuckets is now a word in the page header. If more bits
are needed than fit into a single word, an external bitmap is
allocated using AlignedAlloc. Storing this on the page header, allows
to remove initial_buckets from the SlotSet. The SlotSet allocation is
then again a power-of-2 in release mode.
Reland of https://crrev.com/c/1906376: Incorrect DCHECK was removed.
WordsForBuckets was simplified and a test was added for it.

This is a reland of 5bddc0e142
The original CL was speculatively reverted as it was suspected to
cause failures on the non-determinism bot. This was ultimately
confirmed to not be the case, so this CL is safe to reland as-is.

Design doc: bit.ly/v8-repl-mode
This CL allows the usage of 'await' without wrapping code in an async
function when using REPL mode in global evaluate. REPL mode evaluate
is changed to *always* return a Promise. The resolve value of the
promise is the completion value of the REPL script.
The implementation is based on two existing mechanisms:
- Similar to async functions, the content of a REPL script is
enclosed in a synthetic 'try' block. Any thrown error
is used to reject the Promise of the REPL script.
- The content of the synthetic 'try' block is also re-written the
same way a normal script is. This is, artificial assignments to
a ".result" variable are inserted to simulate a completion
value. The difference for REPL scripts is, that ".result" is
used to resolve the Promise of the REPL script.
- ".result" is not returned directly but wrapped in an object
literal: "{ .repl_result: .result}". This is done to prevent

Until now, the in-object properties on JSObject have been invisible to
tools using the postmortem debugging library. With this change, those
tools will get enough information to show a flat list of property
values. This is still less powerful than the runtime printers, which can
show the corresponding key for each value, but it's a big step up from
manually inspecting memory.
This change basically requires a reimplementation of
Map::GetInObjectProperties for postmortem debugging. I'm not
enthusiastic about duplicating this logic, but it's pretty small and I
don't see any good alternatives.
As a drive-by cleanup, I moved some inline string literals into a batch
of constexpr char arrays.

This change defines a way that v8_debug_helper can describe object
fields which are packed structs, and uses it for the "descriptors" field
in DescriptorArray.
In more detail:
- debug-helper.h (the public interface for v8_debug_helper) adds a size
and an optional list of struct properties to ObjectProperty.
- debug-helper-internal.h mirrors those changes to the internal class
hierarchy which maintains proper unique_ptr ownership.
- In src/torque/class-debug-reader-generator.cc,
- Some existing logic is moved into smaller functions.
- New logic is added to generate the field list for structs. Example
output is included in a comment above the function
GenerateGetPropsChunkForField.

This reverts commit 1ec2ca266f.
Reason for revert: Preparing for re-enabling pointer compression.
Original change's description:
> [ptr-compr] Temporarily enable double fields unboxing
>
> We are not shipping ptr-compr in M79 on x64 because chromium:1009439
> blocks 31-bit Smis on 64-bit architectures, so these's no point in
> disabling double fields unboxing.
>
> This CL will be reverted after the M79 branch point.
