This CL exposes the `recurring` flag on the experimental async stack tagging API which was implemeted in the following CL: https://chromium-review.googlesource.com/c/v8/v8/+/3212506 It serves as a prototype to check if such an API is suitable for improving stack traces for frameworks which split up tasks across multiple frames, yielding back to the main thread when some time budget is consumed.

This CL introduces a dedicated API to retrieve the current (w.r.t. the JS stack) script name or sourceURL. Currently, API clients will collect multiple stack traces in increasing sizes to accomplish the same goal. The new method walks the JS stack in the same way as the stack trace collection mechanic but doesn't create/allocate stack info or callsite objects along the way.

As described in https://crbug.com/1287476, the fact that the AsyncEventDelegate is currently implemented on top of the PromiseHooks causes performance problems and makes it difficult to reason about the exact (observed) semantics; this is because for this we intercept every JSPromise creation (via PromiseHook::kInit) and walk the synchronous stack at that point to see if we find one of Promise#then(), Promise#catch() or Promise#finally() on the stack. And if we do so, we report that to the AsyncEventDelegate (which is implemented in the inspector and will then do the async stack/stepping logic on top). This CL introduces dedicated instrumentation for Promise#then(), which is also called from Promise#catch() and Promise#finally(), and uses that instrumentation for the purpose of the AsyncEventDelegate. It also adjusts the stack walk to not always walk the full stack (which might lead to wrong results when calls to Promise#then(), which itself can call back into user JavaScript, are found deeper in the stack), but instead only check the top-most builtin frames and whatever user JavaScript frame is underneath it. On the standalone.js (from https://crbug.com/1287476#c1), when run with the DevTools default of maxDepth=200, we go from around 4.00ms to around 0.36ms. For everything that does not call Promise#then() - either explicitly or implicitly - or `await`s, there's now no observable performance impact of turning on the AsyncEventDelegate.

The fast path has an early return if the two inputs are the same object. However, this was missing the check that the receiver is not undefined required by the spec. This fixes it by first checking that the receiver is a string and only afterwards checking for reference equality.

Shell::FetchModuleTree assumes that the module at file_name wasn't already fetched. Shell::ExecuteModule is calling into FetchModuleTree without checking if the module is already in the module map, violating this assumption. This change fixes this by having Shell::ExecuteModule check for the existence of the module before calling into Shell::ExecuteModule, the same way that Shell::DoHostImportModuleDynamically does.

Similar to the case of fixed registers, we need to consider both cases: A SIMD register might collide with either the low or high FP register, or the FP register might collide with a previously allocated SIMD register.

For getting from one SIMD "sibling" register to the other, the mid tier register allocator was relying on the indexes of the two registers to be {2N} and {2N+1}. This is only true for lower SIMD registers; later registers can be at {2N-1} and {2N} instead, because of holes in the allocatable double registers (e.g. d13-d15 are not allocatable currently on ARM). We can rely on other facts though: 1) The two aliasing registers are always successive. 2) A SIMD register code always maps to the lower register index. 3) We can get from an F32 register code to F64 and from F64 to S128 by shifting one bit to the right (this is what {RegisterConfiguration::GetAliases} uses). This bug was uncovered by running the existing cctest/test-code-generator/FuzzAssemble* tests with either --turbo-use-mid-tier-regalloc-for-huge-functions or with --turbo-force-mid-tier-regalloc. Hence it will be covered by these tests once https://crrev.com/c/3347822 lands.

Following up on https://crrev.com/c/3383775 I realized that we could just use the existing %DebugPopPromise and %DebugPushPromise runtime functions, which do exactly the same job as %DebugAsyncFunctionFinished and %DebugAsyncFunctionResumed, and are already used in other places of promise instrumentation. We can also remove %DebugAsyncFunctionEntered and utilize the logic in NewJSPromise() to deal with the various promise hooks, and otherwise go with %DebugPushPromise for the debugger side.

The Isolate might not be aware that remapped builtins are used (see Code::OffHeapInstructionStart()), so always try to lookup PC in the remapped builtins if they are available. This is a follow-up to https://chromium-review.googlesource.com/c/v8/v8/+/3379817.

ScopeInfo will contain either inlined (array) local names or a hash table (names => index) containing the local names. We abstract iteration with LocalNameIterator and remove ContextLocalName since accessing a local name by index in the hash table would be expensive. This CL only implements the iterator for the array.

kScopeInfoMaxInlinedLocalNamesSize is a threshold for inlined storage, otherwise local names will be stored in a hash table.

ScopeInfo will contain either inlined (array) local names or a hash table (names => index) containing the local names. If we have the local names inlined, we should save the class variable context slot index. If we have a hash table instead, we should save the class variable offset in the internal hash table storage.

This CL removes the global IsValidBackingStorePointer function and turns the DCHECKs that ensure that sandboxed pointers point into the sandbox, which essentially cover the same condition, into CHECKs. This is mostly to facilitate debugging during the initial rollout, and the CHECKs can later be turned back into DCHECKs. In addition, this CL adds a fallback to a partially-reserved sandbox when sandboxed pointers are enabled and when the regular initialization fails.

Since ManualGCScope changes marking flags it should finalize any ongoing GC before changing the flags. Otherwise, the GC may observe inconsistent state.
