We used to recompile WasmCapiCallWrappers whenever they were needed, but never garbage-collected them, which caused a memory leak when many short-lived instances of the same module were created. This patch makes the wrappers cacheable and caches them, which avoids both repeated compilation effort and the unbounded memory growth. Drive-by cleanup: unify WasmCapiFunctionData with the other Wasm*FunctionData classes by making it inherit from WasmFunctionData.

When setting a breakpoint on a line (in the DevTools front-end), the front-end sends a columnNumber of 0 and the inspector automatically resolves the actual location (in bytecode execution order). In order to also support changing source code, the inspector memorizes a text hint, and uses that to adjust the location upon reload. This hint was however taken based on the original line and column numbers, rather than the resolved location, which causes trouble when syntactic order doesn't match execution order, as in case of `await o.m()`. In order to address that we now remember the textual hint based on the resolved location.

Port 2a43f8c4 Original Commit Message: Inline the RememberedSetAction and SaveFPMode flags directly into the RecordWrite stubs: - Save two register for input arguments - Avoid branches in the RecordWrite stubs We end up with 2 stubs for the EphemeronKeyBarrier and 4 stubs for RecordWrite. Due to more inlined calls we have roughly 1KiB more builtins code for RecordWrite currently. We will address this in the future by splitting out common code into a separate stub. There is no additional code size overhead for EphemeronKeyBarrier. This saves 4 to 8 bytes on x64 per RecordWrite call and 2.5% sparkplug code size reduction on d3.min.js.

CollectionRequested was used exclusively on the main thread when a background thread requested a GC. The main thread never used SafepointRequested at any time. Now with the shared GC we might need to stop multiple isolates in a safepoint in the future. In such a situation we would need to use SafepointRequested also on the main thread. This CL prepares V8 for this situation by using SafepointRequested instead of CollectionRequested and friends on the main thread. The slow path of Safepoint(), Park() and Unpark() will check in the future whether the main thread needs to halt for a shared GC or needs to perform a local GC. At the moment, simply performing the local GC is still enough.

If fuzzers pass a low --wasm-max-initial-code-space-reservation limit, we might run into a DCHECK/CHECK failure because the "overhead" per code space (for jump tables) is more than half of the reserved code space (DCHECK) or actually bigger than the reserved code space (CHECK). This CL fixes that by explicitly failing with an OOM message in that case. This should only happen if that testing flag is set. I do have a test case for this (reduced from the ClusterFuzz report) but it needs >20000 functions (to make the jump tables big enough to fail the checks), so it runs really slow (>90 seconds in debug). Since the failure only happens with a testing flag, I think it's acceptable to fix this without a regression test.

Our synchronization protocol for top and limit only guarantees that we read the new limit in case we read the new top. However, it could happen that we read the old top but the new limit. In the allocation slow path we reset both top and limit to 0 first and then reset it to the free list allocation boundaries. With --no-inline-new we are changing top/limit a lot, so it could happen that we read the old value for top (0) but a regular address for limit. In such cases large parts of the heap would be incorrectly considered pending. Handle these cases here by checking that top is non-zero. This is temporary fix, we believe that it is at least theoretically possible to read non-0 but non-consistent values for top/limit as well. This will be addressed in a subsequent CL.

Using kAssumeMemoryFence works around the fact that the graph stores handles (and not refs). The assumption is that any handle inserted into the graph is safe to read; but we don't preserve the reason why it is safe to read. Thus we must over-approximate here and assume the existence of a memory fence. Note this is only valid if all spots that insert handles into the graph ensure that the handle can safely be read. In the future, we should consider having the graph store ObjectRefs or ObjectData pointer instead, which would make new ref construction here unnecessary.
