In the implementation of WebAssembly.compileStreaming and
WebAssembly.instantiateStreaming, we did not handle the case where the
input, which is a Promise, gets rejected. When this Promise got
rejected, the Promise returned by compileStreaming remained pending
forever.
With this CL, the rejection object of the input Promise gets forwarded
to the result Promise.
I also extended the --wasm-test-streaming flag to provide
WebAssembly.compileStreaming and WebAssembly.instantiateStreaming
in d8. The difference to the Chrome versions of these function is
that d8 does not know about Response objects. That's why in d8
compileStreaming and instantiateStreaming expect a Promise to an
ArrayBuffer or a TypedArray and not to a Response object.
