Port ea7499f5 Original Commit Message: Currently, we context allocate all parameters for generators. With this CL, we keep arguments on stack (unless they escape to inner closure) and copy them between the stack and the generator's register file on suspend/resume. This will save context allocation in most cases. - Suspend copies arguments and registers to the generator. - Resume copies only the registers from the generator, the arguments are copied by the ResumeGenerator trampoline.

At the moment, WebAssembly.instantiate(bytes) is implemented by desugaring it to WebAssembly.compile(bytes).then(WebAssembly.instantiate). The problem is that the {then} in this snippet is observable. With this CL I introduce a CompilationResultResolver which allows to do the desugaring internally and thereby make the {then} unobservable. Unfortunately the result of WebAssembly.instantiate(bytes) is different than the result of WebAssembly.instantiate(module). Therefore I also introduced an InstantiationResultResolver for symmetry with WebAssembly.compile.

We store deopt inline frames for all functions when we receive the code creation event. We only ever use this information for code which is deoptimized. Given that we receive code deopt events, we can just store this information when the code is deoptimized. At the time of the code deopt event, we also know the associated deopt_id. That means we don't need to store a map of deopt_ids to vectors of frames, because we will only ever access the frames for the deopt_id that is already set. This means we store way less data, particularly for long-running processes which see fewer deopts. This saves 10MiB peak memory on the node server example.

This CL uses the new function pointers and generic features of Torque to improve the performance of TypedArray.p.sort. Instead of one Load/Store builtin that dispatches at runtime based on the element kind, there are now many small builtins (one for each element kind). The sorting algorithm then uses function pointers to those small builtins, which get set once.
