Prototype v128.{load,store}{8,16,32,64}_lane on Big Endian machines. Lood/Stores need to be reversed manually on BE machines and as such LoadLane and StoreLane opcodes cannot be done in a single instruction. Therefore we divide them into separate "Load/Store" and "operation" nodes.

Currently, all runtime C++ code generated for Torque macros all goes into a single .cc file and corresponding header. This is simple, but limits how we can use that generated code. For example, field accessors are generally expected to be inlinable at compilation time (not relying on LTO). This change updates the Torque compiler to output runtime C++ code into the same *-tq-inl.inc files that contain implementations of member functions for generated classes. All Torque macros transitively called from the top-level macros are included in the same file, to avoid any need for these generated files to #include each other. These macros are emitted within per-file namespaces to avoid multiple-definition build failures.

We didn't pass a script ID with the code creation events for profiling. This made DevTools lose the connection to the wasm script, hence jumping from the profiler entry to the source did not work. This CL changes the timing of code logging a bit such that the script is always allocated before logging. In the queue of code to be logged we then also store the script ID, and finally set it on the {CodeEntry} object.

Although every Primitive is a Data, the Cast operations for the subclasses of Primitive do not allow casting directly from Data to the subclasses without first going through Value. Because of this, Primitives extracted from a V8::FixedArray require two casts to get to the "real" type. Thus, as a convenience to embedders, this change makes it possible to cast directly from Data to all the subtypes of Primitive. Also, this change makes the parameter names in the declarations match those in the definitions, though there does not seem to be a universally followed convention regarding these.

Import wrappers were only logged if logging was enabled during compilation. If the profiler is enabled later, and regular wasm code is logged via {NativeModule::LogWasmCodes}, the import wrappers were missing. This CL fixes the long-standing TODO, and adds tests which triggered that code path. Those tests were hanging before because the expected functions did never appear in the profile. Drive-by: If {WasmEngine::LogOutstandingCodesForIsolate} detects that code logging is disabled by now, it should still clear the {code_to_log} vector.

For logging existing functions, currently walk the heap four times: 1) For getting the number of JS Code objects, 2) for getting the actual JS Code objects, 3) for getting the number of wasm code objects, 4) for getting the actual wasm code objects. This CL refactors this to do only two heap walks (one for JS, one for wasm). It also avoids the use of the brittle {ScopedVector} and uses a {std::vector} instead.

Previously V8 would wrap the WebAssembly.Memory backing stores into Uint8Arrays and report that as memories, but that's confusing to the developer, since that's not what's really being used. The way that DevTools presents the backing stores of memories, it's still perfectly possible to get hold of an Uint8Array if that's what the developer is looking for. To make it possible to easily identify the WebAssembly.Memory objects in the DevTools front-end (in particular for the memory inspector) we add a 'webassemblymemory' subtype to the Chrome DevTools Protocol. We also improve the description for the memories to include the number of active pages.
