[JSC] Improve our bound function implementation
https://bugs.webkit.org/show_bug.cgi?id=205327 Reviewed by Keith Miller. JSTests: * microbenchmarks/function-bind-no-inlining-repeat-call.js: Added. (assert): (test): (test2): (foo): (let.start.Date.now): * stress/bind-args.js: Added. (shouldBe): (test): (test2): Source/JavaScriptCore: This patch improves Function#bind, and calling bound function with bound arguments. 1. Rename CallFrameSlot::argumentCount to CallFrameSlot::argumentCountIncludingThis. 2. Do not include name in NativeExecutable for JSBoundFunction. Putting name in NativeExecutable is assuming that function + name pair is almost identical. This is true in host functions except for JSBoundFunction. JSBoundFunction should hold its name in JSBoundFunction. 3. Cache NativeExecutable for JSBoundFunction in the VM. We use a hash-map in JITThunk for NativeExecutables because we assume that host-function creation cannot be done by the user program: each executable is pre-defined to exactly one object by the environment, and there is no way to create host-functions repeatedly from the user-program. The only exception to this is JSBoundFunction so caching it on the VM avoids the hash-map lookup. This is not true for JSBoundFunction. 4. ThunkGenerator should support JSBoundFunction call with bound arguments. It turns out that Speedometer2/React-Redux-TodoMVC is using bound function with bound arguments. Additionally, it is used. This is really bad: when dispatching an event, we first call this function from C++, entering JS world, going back to C++ world again, and entering JS world to call bound function again. By using ThunkGenerator, we can eliminate this back and forth by directly calling the bound JS Executable from the thunk. Previously, bound arguments are stored in JSArray. But it is difficult to access them from thunk since we need to consider have-a-bad-time case. Instead, we use JSImmutableButterfly to save bound arguments so that JIT thunk can quickly access arguments. To capture arguments as JSImmutableButterfly in JS world, we introduce op_create_arguments_butterfly, and handle it in all tiers. 5. It turns out that eager materialization of "length" in JSBoundFunction takes long time while it is rarely used. This patch makes length lazily reified for JSBoundFunction. 6. To make Function.prototype.bind faster, we track whether "name" and "length" properties of JSFunction is modified or not. This skips has-own-length-property check, which makes Function.prototype.bind 11~% faster. Combining things above, creation of JSBoundFunction is 80~% faster. And calling bound function with bound arguments is 3~x faster. This improves Speedometer2/React-TodoMVC by ~3%. * builtins/FunctionPrototype.js: (bind): * bytecode/AccessCase.cpp: (JSC::AccessCase::generateImpl): * bytecode/AccessCaseSnippetParams.cpp:
