      [heap] Reduce size of possibly empty buckets · 80caf2cf
      Dominik Inführ authored 
      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.

      Revert "[ptr-compr] Temporarily enable double fields unboxing" · be306c92
      Igor Sheludko authored 
      This reverts commit 1ec2ca26.

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.
