This breaks up the existing {max_mem_pages()} method and the {kSpecMaxMemoryPages} and {kV8MaxWasmMemoryPages} constants into two versions for memory32 and memory64, respectively. For now, the limits are still the same. Some checks and clamping is moved to earlier places where we still have the information whether a memory is 32 or 64 bit. We also store that information in the WasmMemoryObject and use this for knowing the maximum for growing. This CL is not supposed to change any observable behaviour.

Currently the Isolate is gotten off of the object that the operation is being performed on. GetDataProperty may end up using a per-Isolate lookup cache, which is not threadsafe when the Isolate is shared. Plumb the executing, non-shared Isolate through.

TurboFan reads the value in HeapNumber, and TSAN detects a data race between this read and sets on the main thread elsewhere. We mark this as relaxed atomic (meaning, correct value of the read is not guaranteed). The compiler uses the dependency mechanism to re-read the value safely on the main thread later, and aborts compilation if a change is detected.

There are two different limits for the maximum memory size in WebAssembly: 1) A 4GB limit which is the same on all platforms, and is observable for JS programs. It is used to limit the allowed declared maximum size of a wasm memory. 2) A potentially lower limit (2GB on 32-bit systems, 4GB otherwise) which can be further limited using a command-line flag. This limit is used whenever actually allocating or growing a wasm memory. This limit is not directly observable, but we make sure that no wasm memory will ever be bigger than this limit. The second limit is the one we should check against when allocating or growing memory, while the first limit should be used when validating a module (or the parameters for WebAssembly.Memory). The compiler can rely on no memory being bigger than the second limit, which again is never bigger than the first limit. This CL adds some more documentation to the two limits, and cleans up all usages. This also makes {kPlatformMaxPages} and {kMaxMemoryPagesAtRuntime} obsolete.

It could happen (e.g. with --stress-background-compile) that the main thread blocks for a background thread but the background thread requests a GC from the main thread. This would result in a deadlock. Avoid this by parking the main thread for potentially blocking operations and allow allocations while the main thread is parked. This CL introduces new states for the main thread: CollectionRequested and ParkedCollectionRequested. These states will force Safepoint(), Park() and Unpark() on the main thread into slow paths. The slow path can then perform a GC on the main thread - right before parking or after the main thread got unparked.

This unifies {max_initial_mem_pages} and {max_maximum_mem_pages} into {max_mem_pages}. The {CompilationEnv} constructor was incorrectly using the former instead of the latter anyway. This did not really matter though, since they typically have the same value. Also, there is not a single test that sets --wasm-max-mem-pages-growth.

This patch introduces a new LocalIsolate and LocalFactory, which use LocalHeap and replace OffThreadIsolate and OffThreadFactory. This allows us to remove those classes, as well as the related OffThreadSpace, OffThreadLargeObjectSpace, OffThreadHeap, and OffThreadTransferHandle. OffThreadLogger becomes LocalLogger. LocalHeap behaves more like Heap than OffThreadHeap did, so this allows us to additionally remove the concept of "Finish" and "Publish" that the OffThreadIsolate had, and allows us to internalize strings directly with the newly-concurrent string table (where the implementation can now move to FactoryBase). This patch also removes the off-thread support from the deserializer entirely, as well as removing the LocalIsolateWrapper which allowed run-time distinction between Isolate and OffThreadIsolate. LocalHeap doesn't support the reservation model used by the deserializer, and we will likely move the deserializer to use LocalIsolate unconditionally once we figure out the details of how to do this.

Allow "iterative" finalization when off-thread finalization is enabled, meaning that each compiled function is finalized immediately after compilation, rather than all functions being first compiled and then finalized. This is what we do on the main thread, and it reduces peak Zone memory usage by being able to discard empty compilation Zones earlier. One necessary functionality for this was being able to defer the finalization of asm.js functions until the main thread pause, since they can't be finalized off-thread -- previously we would just bail out of doing the off-thread finalization if any inner function was asm.js.

This patch unfies the finalization logic between the various unoptimized compilation paths in compiler.cc, taking the various post-processings and fixups needed for off-thread finalization and performing them in the same order for the other finalizations. It also unifies the general compilation path between streaming script compilation, main-thread script compilation, and main-thread lazy compilation, making the main-thread paths both use an iterative execution and finalization, and making all three use the same job helper methods and overall finalization helper.

asm-to-wasm doesn't support off-thread finalization, so disable it if an asm compilation job is successfully executed. Note that in the future, we could instead have a hybrid off-thread and main-thread finalization for mixed JS and asm.js scripts, but for now that's probably unncecessary.

Add the remaining missing templatizations to allow an initial wiring in of the off-thread factory into streaming compilation finalization. The off-thread finalization is behind a flag, disabled by default: --finalize-streaming-on-background When the flag is enabled, background tasks will perform perform the finalization during their background execution, and will release the parser and compilation jobs once they are no longer needed. The implementation is complete enough for performance testing, but not enough for launch. Notably, there is no support for: * Class boilerplates (the code is marked unreachable), * Exceptions during finalization, i.e. parse/compile warnings/errors, * Allocation sampling, * Logging, * Asm.js, * Parallel complication tasks * Forced source positions (for "NeedsDetailedOptimizedCodeLineInfo()") This patch also adds some tracing events for the various stages of the off-thread finalization (including the main-thread merge) for further performance improvements.

The asm.js offset table exists in two forms: Delta-encoded in a byte array, as generated during asm translation, and decoded, for faster lookup. This CL moves the encoded version from the {AsmWasmData} and {WasmModuleObject} to the {WasmModule}, and stores it off-heap in a C++ array instead of a {ByteArray}. Also, it moves the decoded version off-heap by storing it in a C++ data structure that makes lookup easy, instead of encoding it again in another {ByteArray}. This change is a nice refactoring in itself, but it also prepares adding more information to the offset table. For reconstructing the source code of an asm.js function, we will need to store the start and end offsets of the whole function as well (see linked bug).
