      Revert "[heap] Optimize time to reach global safepoint" · b51a100d
      Dominik Inführ authored 
      This reverts commit 86038ecf.

Reason for revert: Caused TSAN failures

Original change's description:
> [heap] Optimize time to reach global safepoint
>
> Initial support for global safepoints kept it simple by entering a
> safepoint for each of them one after another. This means
> time-to-global-safepoint is the sum of all time-to-safepoint operations.
> We can improve this slightly by splitting up the safepoint iteration
> into two operations:
>
> 1) Initiate safepoint lock (locks local_heaps_mutex_, arms the barrier
>    and sets SafepointRequested flag for all client threads)
> 2) Block until all runnning client threads reach a safepoint
>
> We now perform operation 1) for all clients first and only then start
> with operation 2).

      cppgc: Reflush in construction objects after parallel marking · 529b8d3c
      Omer Katz authored 
      Concurrent marking could still push object to the in construction
worklist after it is emptied at the start of the atomic pause.

      [wasm][turbofan] Refactor/improve global operations · 2b985fb8
      Manos Koukoutos authored 
      Changes:
- Refactor all global base and offset computations into a single
  function and simplify GlobalGet and GlobalSet.
- Remove unneeded pointer arithmetic in the simd case. This enables the
  use of object operators, including LoadImmutableFromObject, which
  might enable more loads to be eliminated.

      [wasm][turbofan] Immutable object operators · 4113cf64
      Manos Koukoutos authored 
      Design doc: bit.ly/36MfD6Y

We introduce simplified operators LoadImmutableFromObject and
InitializeImmutableInObject. These are lowered to Loads and Stores like
LoadFromObject and StoreToObject.
We split CsaLoadElimination::AbstractState in two HalfStates,
which represent the mutable and immutable component of the state.
Immutable operators in the effect chain modify the immutable half-state,
and plain operators modify the mutable half-state. The immutable part is
maintained through write effects and loop headers. Immutable
initializations do not lookup and kill previous overlapping stores,
assuming each offset cannot be initialized more than once.
