We recently changed embedded builtins to be emitted as raw assembly files during the build process in order to support MSVC (which doesn't support inline assembly on x64). Ninja uses ml.exe / ml64.exe as the assembler on all Windows builds (msvc & clang); these unfortunately don't support large data streams well and can take over 5 minutes for embedded.S. With this CL we work around this by going back to inlined assembly for clang Windows builds.

Adds a new field rare_data of type FunctionTemplateRareData to FunctionTemplateInfo and moves 8 others which are unset on 90% of FunctionTemplateInfo objects to this field. Getters like prototype_template() are changed to GetPrototypeTemplate() to indicate they're not trivial. The setters are replaced with static methods (e.g. SetPrototypeTemplate) that take an Isolate and the template object, since they can now perform allocation.

Many tests were already skipped in debug mode, but they kept running on CQ which sets dcheck_always_on, probably equally slow.

Previosly, LoadArrayElement assumed that the array is a FixedArray. The PropertyArray and WeakFixedArray pretended to be a FixedArray and had static asserts about length offsets. This patch make LoadArrayElement generic and uses a new LoadArrayLength function to fetch the length of the array without hard-coding the length offset.

This CL moves optimization capabilities from typed lowering to typed optimization. In particular, this allows retyping of Speculative to number optimizations depending on their input types.

Moves allocation of the WasmModuleObject for asm.js code out of SyncCompileTranslatedAsmJS since that is called when we are compiling the native context independent SharedFunctionInfo and the WasmModuleObject requires a native context. Instead save the members required to create the object in the AsmWasmData and create it during module instantiation. Note: since the Wasm module is an implementation detail for asm_wasm code and isn't exposed, this doeesn't have semantic change for asm.js code. As part of this change, the AsmWasmData is changed from a FixedArray to a dedicated struct. Some logic is also moved from module-compiler to wasm-engine to make the seperation between Wasm SyncCompile and AsmJS SyncCompile more clear.

Sigurd Schneider authored
Load elimination is running together with to dead code elimination, the latter of which might eliminate allocations (in particular FinishRegion nodes). These are treated as alias nodes by load elimination, and load elimination does not immediatelly learn that a node has been disconnected. This causes load elimination to access the inputs of dead code eliminated nodes while resolving renames, which causes nullptr dereferences. This CL modifies load elimination to not resolve to a nullptr alias but simply stop before that.
