macOS’s `readlink` doesn’t support the `-f` flag. By using `realpath` we get the same functionality with added support for macOS. Finally, this patch adds `v8` and `v8-debug` to the completion command. These are the binary names used by jsvu [1].

Processing StateValues into operands is one of the most costly parts of instruction selection. As it happens, StateValues are shared by many nodes, and so we are unecessarily reprocessing the same StateValues multiple times. This CL introduces caching for the processed StateValues enabling very fast emitting of operands for subsiquent instructions with the same StateValue. The hitrate for the cache is higher than 90% on most optimizations.

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.

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.

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.
