      [shared-struct] Shared Array Initial prototype · afb26623
      Luis Fernando Pardo Sixtos authored 
      Initial implementation for concurrent shared arrays. Current implementation exposes a `SharedArray` constructor, but its syntax might
change in the future.

Shared arrays can be shared across Isolates, have a fixed size, have no
prototype, have no constructor, and can only store primitives, shared structs and other shared arrays. With this CL shared structs are also allowed to store shared arrays.

The Backing storage for the SharedArrays is a `FixedArrayBase`. This CL introdces a new ElementKind: `SHARED_ARRAY_ELEMENTS`. The new kind should match the overall functionality of the `PACKED_SEALED_ELEMENTS` kind, but having it as standalone kind allows for easier branching in CSA and turbofan code.

      [wasm][refactor] Rename some symbols · 15821ebb
      Manos Koukoutos authored 
      - Rename WasmTrapElemSegmentDropped -> WasmTrapElemSegmentOutOfBounds.
- Rename WasmArrayInitFromData -> WasmArrayInitFromSegment, in
  anticipation of array.init_from_elem.
- Rename InitExprInterface::result_ -> computed_value_, to
  distinguish it from the {result} values. Also, rename
  generate_result() -> generate_value().
- Drive-by: Restructure Runtime_WasmArrayInitFromSegment.

      [ic] name Set/Define/Store property operations more consistently pt.2 · cf5ce194
      Joyee Cheung authored 
      As a follow-up of
https://chromium-review.googlesource.com/c/v8/v8/+/3481475,
this renames a few more operations related to property stores to keep
them consistent and adds comments to explain about what they do.

Summary of the renamed identifiers:

- SetPropertyInLiteral -> CreateDataProperty: this implements
  [[CreateDataProperty]] in the spec which does [[DefineOwnProperty]]
  instead of [[Set]], so rename for clarity.
- IsStoreIC(), IsStoreICKind() -> IsSetNamedIC(), IsSetNamedICKind():
  these only check whether the feedback kind is kSetNamedSloppy or
  kSetNamedStrict, so the scope can be narrowed.
- StoreMode::kOrdinary -> StoreMode::kSet: this implements [[Set]]
  in the spec and is used by both KeyedStoreIC and
  StoreIC to set the properties when there is no feedback.
- StoreMode::kInLiteral -> StoreMode::kDefineKeyedOwnInLiteral:
  this implements [[CreateDataProperty]] while expecting the receiver
  to be a JSObject created by us (the `InLiteral` part). Prepend
  `DefineKeyedOwn` to it so that it's more aligned with other
  StoreModes - it should be possible to just merge this into the
  more generic StoreMode::kDefineKeyedOwn later.
- KeyedStoreGenericAssembler::SetProperty ->
  KeyedStoreGenericAssembler::StoreProperty: these helpers are used by
  both define and set operations, distinguished with the StoreMode,
  so rename it to the more generic StoreProperty.

  --experimental-wasm-gc. Add the same capability in
  wasm-module-builder.js.
