Bug 1503012 - Part 2: Shim some web-platform-tests for streams into the jit-tests. r=arai,chmanchester

This is an egregious hack. The web-platform-tests were not meant to run in the shell.

The eight tests that are included are the ones that we pass with flying colors.
In most of the others, we still have a failure or two.
