Bug 1478533 - Add a static_assert for WeakMap. r=jonco, mccr8 If an object is used as a WeakMap key, its TraceKind should be added into CC graph, so adding a static_assert to make sure this.

Bug 1506660 - Dispense with TODO comments about bytesWritten in ReadableStream implementation. r=till The first comment appears in ReadableByteStreamControllerPullSteps. It's OK to delete it because we just asserted that there are no pending read requests (step 3.a.). The second comment appears in JS::ReadableStreamUpdateDataAvailableFromSource. It's OK to delete this one because it's in the hasDefaultReader branch. Default readers don't have read requests that care about the number of bytes available.

Bug 1503718 - Part 2: Use the `unwrapped` prefix. Covers spec sections 3.5 to 3.9. r=tcampbell ReportArgTypeError is replaced with a new helper function template, UnwrapAndTypeCheckArgument. The old function used the expression decompiler, but that seems unhelpful here; the new code uses InformalValueTypeName on the actual argument value.

Bug 1503718 - Part 1: Use the `unwrapped` prefix. Covers spec sections 3.2 to 3.4. r=tcampbell Each patch in this stack deletes comments that are redundant with the new naming convention. In ReadableStreamTee_Cancel, we have a variable named `unwrappedReason` whose purpose is to create a properly wrapped verison of `reason`. It's a little vertiginous. But I think this is what the new convention demands and it's not so bad. Also in ReadableStreamTee_Cancel, step 4.c., we wrap `cancelResult`, which does not have an `unwrapped` tag. This is because we switched realms between the declaration of `cancelResult` and the line of code where we're going to use it. I think this just means the convention is never going to make all correct code obviously-correct and all wrong code obviously-wrong. Still an improvement.

Bug 1506656 - Part 2: Silence a dead code warning. r=jwalden This renames the other CreateReadableByteStreamController signature, since the two seem different enough to warrant distinct names. Differential Revision: https://phabricator.services.mozilla.com/D11680

Bug 1506656 - Part 1: ReadableStream controller constructors should throw unconditionally. r=jwalden They already do, as it's impossible for content to get hold of a stream with no controller, which is the only kind of object our existing code would accept. But the spec is now more direct, and the code should match it. Differential Revision: https://phabricator.services.mozilla.com/D11679

Bug 1450219 - Make sure not to lose track of focus when we rebuild the inner fields. r=Gijs Removing the inner field while focused nulls out the active element, without a blur event of course, so this means that we left the :focus state in the input set incorrectly, plus that we actually lost focus.
