Previously, the following call sequence was always made when creating resulting subsetted TypedArray: 1) TFJ TypedArrayPrototypeSubArray 2) TFS TypedArrayConstructor 3) TFS CreateTypedArray This CL, skips #2 and goes straight to #3 when the default constructor (builtin) is safe to use (IsPrototypeTypedArrayPrototype and !IsTypedArraySpeciesProtectorCellInvalid). Local TypedArrays/SubarrayNoSpecies microbenchmark shows ~35-40% improvement...

See the WebAssembly bulk memory proposal here: https://github.com/WebAssembly/bulk-memory-operations This initial CL adds a wasm experimental flag: `--experimental-wasm-bulk-memory`, and also parsing of passive segments. A passive segment is one that is not copied into the table/memory on instantiation, but instead later via the `{table,memory}.init` instructions. The binary format of passive data segments is unlikely to change, but the format for passive element segments may change (see https://github.com/WebAssembly/bulk-memory-operations/pull/39).

With this change, the return value is not baked into the translations for lazy deoptimization point. Instead, the translation contains a position where the return value(s) should be written by the deoptimizer. The deoptimizer then constructs the frame as it would look before and during the call and then overwrites the relevant slot(s) with the return value(s) from the callee. The advantage is that we do not run the risk of overwriting captured objects in the tranlations. Moreover, the translations correctly reflect the frame during the call (e.g., if it is inspected by the debugger or if an exception is thrown and no value is returned).

After the first decoder error, the streaming processor should not be called again. To enforce this, reset the {processor_} field. This also makes the {ok_} field redundant. Note that this refactoring is also necessary for a future CL which makes the {StreamingProcessor} keep the {AsyncCompileJob} alive. By resetting the processor, we also remove that link.
