Both tables are always updated together and are always accessed together. Thus merge them, reducing code complexity, but also code space and overhead for accessing them during runtime. Instead of two weak global handles, we only need one, which also means one less load for each indirect call. Merging them also improves cache locality, since signature and code address are not stored next to each other in memory, so they will very likely end up in the same cache line.

This uses a temporary file in the mocked d8 script to let d8 flip between FAIL and PASS on rerun. This adds a separate test root with dedicated test suite for testing flakes to no interfere with existing status file configs.

We don't currently inline array builtins if we detect any side effects between the load of the receiver map and the call to the builtin. The introduction of a map check allows us to be more permissive.

If there is no constructor or species updates on Array or TypedArrays, then skip lookups of constructor and species so that we can create a new typed array quickly. This path makes TA.p.slice() 2x faster in fast cases.

This is the implementation of crrev.com/c/866721 for arm. Drive-by change: I simplified the slot index calculation. Original description: At the moment the slot index is encoded in the opcode. This, however, sets an upper limit the slot index which is lower than what we want to have (i.e. < 512). With this change we pass the slot index as an immediate operand, which does not impose limits on the value it contains.

This is the implementation of crrev.com/c/766371 for arm64. Original description: Add the ability to return (multiple) return values on the stack: - Extend stack frames with a new buffer region for return slots. This region is located at the end of a caller's frame such that its slots can be indexed as caller frame slots in a callee (located beyond its parameters) and assigned return values. - Adjust stack frame constructon and deconstruction accordingly. - Extend linkage computation to support register plus stack returns. - Reserve return slots in caller frame when respective calls occur. - Introduce and generate architecture instructions ('peek') for reading back results from return slots in the caller. - Aggressive tests. - Some minor clean-up.
