I/O is quite expensive on the bots. This cuts down a bit of it by printing slightly fewer characters per test in verbose mode. This leads to an overall speed improvement of ~20% for large test suites, e.g. Test262 output-collection time goes from ~2m30 to ~2m. The averages to a 5-10% overall speed improvement for slow tryjobs.

This is a reland of b5f37051 Got reverted since it was breaking the bots (https://bugs.chromium.org/p/v8/issues/detail?id=10918) The solution is to keep the JSDataView class as kSerialized but change its method to do a direct heap access. In this way, its map it will still be serialized (which was the cause of the bot failure). In order to keep incrementally skipping serialization, we can introduce new macros that allow a per-method skip of serialization rather than per-class.

Liftoff code is never relocated and never serialized, thus relocation information is not needed. This results in slightly less information being printed when disassembling code, because the disassembler sometimes uses relocation information to show the kind of a call (e.g. internal wasm call vs. builtin call). This is an acceptable regression IMO.

With the --always_promote_young_mc flag the mark-compact collector cannot gracefully handle allocation failures when evacuating the young generation. In some scenarios this causes OOM crashes without invoking NearHeapLimitCallback. This CL ensures that the young generation is evacuated before the old generation because old generation evacuation can be aborted if needed. Additionally, the CL cleans up usages of CanExpandOldGeneration.

For "else" and "catch" statements, the Ref to the end label should only be added if the current block is unreachable, not the parent block. In the added regression test, the "true" block ends in an unreachable state with a stack height less than the target height of the end label. This is valid due to the semantics of unreachable code, but we should not add the Ref in this case because its stack height is invalid.

Since the string-table's data pointer is written inside a mutex, but read outside of it, we need to acq/rel access to it. There's no support in C++ for an std::atomic<std::unique_ptr>, so this patch changes the std::unique_ptr<Data> into a std::atomic<Data*>, and handles the deletion manually. StringTable::Data still uses std::unique_ptr as the general pointer-passing contract, we just carefully set and release the unique_ptrs when accessing and setting the StringTable's atomic Data pointer.

This commit adds support for capture groups (as in e.g. /x(123|abc)y/) in the experimental regexp engine. Now every InterpreterThread owns a register array containing (sub)match boundaries. There is a new instruction to record the current input index in some register. Submatches in quantifier bodies should be reported only if they occur during the last repetition. Thus we reset those registers before attempting to match the body of a quantifier. This is implemented with another new instruction. Because of concerns for the growing sizeof the NfaInterpreter object (which is allocated on the stack), this commit replaces the `SmallVector` members of the NfaInterpreter with zone-allocated arrays. Register arrays, which for a fixed regexp are all the same size, are allocated with a RecyclingZoneAllocator for cheap memory reclamation via a linked list of equally-sized free blocks. Possible optimizations for management of register array memory: 1. If there are few register per thread, then it is likely faster to store them inline in the InterpreterThread struct. 2. re2 implements copy-on-write: InterpreterThreads can share the same register array. If a thread attempts to write to shared register array, the register array is cloned first. 3. The register at index 1 contains the end of the match; this is only written to right before an ACCEPT statement. We could make ACCEPT equivalent to what's currently CAPTURE 1 followed by ACCEPT. We could then save the memory for register 1 for threads that haven't finished yet. This is particularly interesting if now optimization 1 kicks in.

Check that a v128 imported global in a Wasm module is initialized with a WebAssembly.Global object. This is technically impossible, because creating WebAssembly.Global of type v128 is an error, and creating one of any other type is a type mismatch. However, we still need this check to avoid hitting an unreachable case when setting the value of the global later on. Also, this is not a validation error, since the v128 restriction is only a Web/JS limitation. Other embedders can choose to do something different with this module with an imported v128 global.
