Emitting bytes to the Uint8Array directly speeds up generation of
binaries enormously.
On the limits-any.js spec test (which creates huge modules), the
execution time of an optdebug build reduces from 286 seconds to 61
seconds.

In the wasm streaming decoder error position test, do also check the
error messages generated. This revealed messages that were not quite
fitting and some that were formatted differently than the majority.

We often use raw assertPromiseResult with {success ==
assertUnreachable} for that. Having a separate helper increases
readability and allows us to generate consistent (and better) error
messages.

We noticed that almost every call site were loading both files,
the split isn't necessary anymore.
In some message tests, removed the absolute line number to allow future
changes.

The flag is on by default, so we don't need to specify it. More
importantly, the tests are expected to work for any value of that flag.
So don't force the flag but use whatever the test variant chooses.
Note that in streaming-compile.js, the flag was accidentally specified
as '-async-compilation'. I also removed that one.

This patch introduces assertPromiseFulfills and assertPromiseFulfills as
a replacement for assertPromiseResult because it’s more JavaScript-y.

In this CL I implement streaming compilation for WebAssembly,
as described in the design doc I have sent out already.
In this implementation the decoding of sections other than the
code section is done immediately on the foreground thread.
Eventually all decoding should happen in the background. I
think it is acceptable to do the decoding on the foreground
thread for now because I have finished it already, and
decoding in the background would add even more complexity to
this CL.
