We had two similar methods (HasOnlyStablePrototypesWithFastElements and HasOnlyStablePrototypesWithFastElementsHelper) which seemed to have been defined to be used in different places, but they were used in only one place each. We can specialize those methods based on their uses and not worry about the other cases.

Most of Map's bit_field (as in not 2 or 3) accessors are not set after construction e.g. is_callable. They are also not used as a synchronization point. From the compiler's point of view, they can be set as non-atomic. There are two accessors (`prototype_slot` and `non_instance_prototype`) that have to be atomic for concurrent marker reasons (relaxed is fine for them).

Allocate the TryInfo in a unique_ptr to ensure that its destructor is called when the corresponding control block is popped from the control stack. In particular, the cache state allocates memory on the heap which is otherwise never freed.

Release-official builds strip error messages from CHECK messages. This can make it difficult to distinguish a CHECK crash location in crash reports. As such, instead of using V8_FatalNoContext, import the IMMEDIATE_CRASH macro from chromium and use that instead, which should cause a crash directly in the instruction stream so that the top stackframe on the crash report directly identifies the CHECK location that failed.

We try and match literal load instructions in order to print a relocation info comment. However, we could be doing it while we're decoding a constant pool.

The register allocator sometimes fails if a parameter node appears twice. This seems to be an issue in the register allocator rather than a global assumption of Turbofan. This CL ensures duplication does not happen in wasm code until the issue is resolved. Changes: - Cache parameter nodes in wasm-compiler. - Use Dead() over Parameter() as placeholder in lowering stages.

Torque generally supports marking things as unused by adding a single underscore to the front of identifiers. For locals, this feature works fine. For macros, it's only half-implemented: attempting to look up a macro that starts with _ fails (as it should), but the compiler also complains if the macro is unused. This change avoids emitting the latter error.
