- Asynchronously load source map from sourceMappingURL - Once loaded, annotate source positions with their original position - Update script panel tooltip to include link to original source - For the above, make DOM.element a slightly more flexible API, allowing defining attributes and children - Also fix ToolTipEvent handling to support nodes. - Shuffle around some code to make createScriptNode async, in case we want to load the source map when building the script node itself. - Drive-by: make source markers a simple backgroundColor when there is only one group.

Now that SimpleStringBuilder is only used in conversions.cc, it can be moved there making it easier to assess its safety and limit further use of this potentially unsafe API. (Additionally unused methods Reset and size are removed).

It was not in sync with the optimization, which relies on inspecting up the length and name fields even for bound functions. To make a now meaningful serializer test actually pass, I have to to make some changes to the test setup. I'm also moving the function name and length index constants from JSFunction to JSFunctionOrBoundFunction for clarity.

StringBuilder and its base class SimpleStringBuilder aren't very safe and are a potential source of memory leaks or double-frees. This removes the StringBuilder class and converts all of its usages to use the standard library. (As a drive-by, this converts std::ostream* to std::ostream& which is more idiomatic C++).

We can get rid of this by deferring adding a new global to the module's globals, and using the current size of globals to determine allowed global indices.

Various field dependencies assume that the receiver map and the field owner map agree on field meta data. That's not necessarily true when the receiver map is already deprecated. We should skip over deprecated maps. - Fix a bug in SerializerForBackgroundCompilation. It used to process even deprecated maps. - Fix a bug in FilterRelevantReceiverMaps. It used to store the original map rather than the new version. - Turn some compilation dependency DCHECKs into CHECKs. - CHECK in MapRef::FindFieldOwner that the map is not deprecated. While there might be valid use cases for calling the underlying Map::FindFieldOwner on a deprecated map, we never want to do that in the compiler. Note that we skip any deprecated maps in JSNativeContextSpecialization's ReduceNamedAccess. That's why I believe the issue could only be observed with --concurrent-inlining and only in the form of a failing DCHECK.

Merges `NativeModuleModificationScope` (with an implementation using Intel PKU, if available, and mprotect otherwise) and `CodeSpaceWriteScope` (for Apple Silicon, where switching to RWX with mprotect is disallowed anyway, so MAP_JIT and thread-local switching must be used). Because `CodeSpaceWriteScope` sounded better (and is shorter), we kept its name (which unfortunately makes the diff a bit harder to read).

The WasmCodeManager was part of the WasmEngine so far, but there is only exactly one WasmEngine. Hence we can pull it out, and also remove the pointer in the WasmCodeAllocator. The argument passed from the single constructor call is now inlined in the constructor itself. Drive-by: Replace "GetPlatformPageAllocator()->CommitPageSize()" by just "CommitPageSize()".

In an effort to merge `CODE_SPACE_WRITE_SCOPE` and `NativeModuleModificationScope`, this CL moves the interface and implementation of the latter into code-space-access.{h,cc}, where the former already lives. No other changes to the code itself.

There is exactly one WasmEngine per process, hence we do not need to store or pass a pointer to it. We just use {GetWasmEngine} (which just reads a global variable) whenever we need it.

The WasmEngine is shared across the whole process, so there is no need to store it in every Isolate. Instead, we can just get it from everywhere on any thread using {wasm::GetWasmEngine()}, which is a simple read of a global.
