Simplify the promise wrapping in await and %AsyncFromSyncIteratorPrototype%.next/return/throw to reuse the PromiseResolve primitive. Now await takes 1 tick instead of 3 on the microtask queue.

Port 733b7c82 Original Commit Message: This introduces the concept of a jump table for WebAssembly, which is used for every direct and indirect call to any WebAssembly function. For lazy compilation, it will initially contain code to call the WasmCompileLazy builtin, where it passes the function index to be called. For non-lazy-compilation, it will contain a jump to the actual code. The jump table allows to easily redirect functions for lazy compilation, tier-up, debugging and (in the future) code aging. After this CL, we will not need to patch existing code any more for any of these operations.

If a call to a builtin is generated at run-time (vs at snapshot time) we don't need to tag the call/jump with relocation info, as the builtin address will not change. The only way to generate a builtin call at snapshot time is via MacroAssembler::JumpToInstructionStream where we keep OFF_HEAP_TARGET. The reloc info for builtin calls and jumps is set to NONE.

Replace all but one Handle<T*>(T*) calls with ones that explicitly pass in an Isolate. Requires plumbing Isolate* through several Parser functions which previously avoided it because of worries about accessing the heap off the main thread. In all off-main-thread cases, isolate will be nullptr and every such function asserts with: DCHECK_EQ(parsing_on_main_thread_, isolate != nullptr); Also deletes unused function ParseInfo::ReopenHandlesInNewHandleScope.
