Reland "Update GetIterator bytecode to load and call object[Symbol.iterator]" This is a reland of 8b89a7c32d2a3dba3254b245b72fe87de5064b8d Reland after disabling the test getting deadlocked with '--gc_stress' flag. The CL was reverted because of the 'wasm/grow-shared-memory' test from the mjsunit test suite deadlocked for the 'gc_stress' variant. This is the known issue (v8:9221) and the deadlocking test is now disabled ( https://chromium.googlesource.com/v8/v8.git/+/1c8981e3f4729b7a8220a8823e0a0d45f2a4b788).

Reland "[interpreter] Add bytecode for leading array spreads." This is a reland of 1c48d52bb1ee9bb28e146c60eda08cd4afaa5745. It turned out that IterableToList doesn't always behave according to the ES operation with the same name. Specifically, it allows holey arrays to take its fast path, which produces an output array with holes where actually "undefined" elements should appear. This CL changes the version of IterableToList that is used for spreads (IterableToListWithSymbolLookup) such that holey arrays take the slow path. It also includes tests for such situations.

Reland "[interpreter] Add bytecode for leading array spreads." This is a reland of 1c48d52bb1ee9bb28e146c60eda08cd4afaa5745. It turned out that IterableToList doesn't always behave according to the ES operation with the same name. Specifically, it allows holey arrays to take its fast path, which produces an output array with holes where actually "undefined" elements should appear. This CL changes the version of IterableToList that is used for spreads (IterableToListWithSymbolLookup) such that holey arrays take the slow path. It also includes tests for such situations. Original change's description: > [interpreter] Add bytecode for leading array spreads. > > This CL improves the performance of creating [...a, b] or [...a]. > If the array literal has a leading spread, this CL emits the bytecode > [CreateArrayFromIterable] to create the literal. CreateArrayFromIterable > is implemented by [IterableToListDefault] builtin to create the initial > array for the leading spread.
