      Revert of [heap] Parallel newspace evacuation, semispace copy, and compaction \o/ (patchset #16 id:620001 of https://codereview.chromium.org/1577853007/ )

Reason for revert:
[Sheriff] Leads to crashes on all webrtc chromium testers, e.g.:
https://build.chromium.org/p/chromium.webrtc/builders/Mac%20Tester/builds/49664

Original issue's description:
> [heap] Parallel newspace evacuation, semispace copy, and compaction \o/
>
> All parallelism can be turned off using --predictable, or --noparallel-compaction.
>
> This patch completely parallelizes
>  - semispace copy: from space -> to space (within newspace)
>  - newspace evacuation: newspace -> oldspace
>  - oldspace compaction: oldspace -> oldspace
>
> Previously newspace has been handled sequentially (semispace copy, newspace
> evacuation) before compacting oldspace in parallel. However, on a high level
> there are no dependencies between those two actions, hence we parallelize them
> altogether. We base the number of evacuation tasks on the overall set of
> to-be-processed pages (newspace + oldspace compaction pages).
>
> Some low-level details:
>  - The hard cap on number of tasks has been lifted
>  - We cache store buffer entries locally before merging them back into the global
>    StoreBuffer in a finalization phase.
>  - We cache AllocationSite operations locally before merging them back into the
>    global pretenuring storage in a finalization phase.
>  - AllocationSite might be compacted while they would be needed for newspace
>    evacuation. To mitigate any problems we defer checking allocation sites for
>    newspace till merging locally buffered data.

      Fix bug where generators got closed prematurely. · 2a0e4225
      neis authored 
      In a generator function, the parser rewrites a return statement into a "final"
yield.  A final yield used to close the generator, which was incorrect because
the return may occur inside a try-finally clause and so the generator may not
yet terminate.

      [turbofan] improved move optimizer readability: MoveKey · 828a2df3
      mtrofin authored 
      MoveKey used to be a std::pair. Rather than expecting the reader to
remember which is "first" and "second", this change makes it a struct
with specific names ("source" and "destination")

      [turbofan] Fixing IMulHigh, which has a temp. · a685180d
      mtrofin authored 
      On Intel, imul clobbers {r|e}ax.  We're missing that in the representation
of the MulHigh intermediate instructions. Fixing, by adding it as a temp,
akin VisitDiv does.

      Stage RegExp subclassing · 8c663eea
      littledan authored 
      This patch stages the first part of RegExp subclassing--defining
Symbol.{match,replace,search,split}, but keeping their original
definitions which are restricted to a RegExp receiver and do not
call out to the core 'exec' method. This is being staged separately
because the two sets of extension points are separate features with
separate functionality. The amount of behavior which is held behind
the flag is very small, just exposing the symbols as properties of
Symbol--the behavior that the String methods call out to these Symbol
properties has already been shipping unflagged.

      Field types can contain at most one map, so we can just use IsClass().
