Page thumbnails hiccups seem to have resolved, so it can be landed again.
This reverts commit 51792b31a36b9539fdd1b4b85abe486c1652b6c4.
Conflicts:
application/basilisk/modules/DirectoryLinksProvider.jsm
Normally we wouldn't need to send any notifications if the actor was
already destroyed, but it can be a VersionChangeOp which needs to
notify its parent operation (OpenDatabaseOp) about the failure.
So SendFailureResult needs to be called even when the actor was
destroyed. Normal operations redundantly check if the actor was
destroyed in SendSuccessResult and SendFailureResult, therefore it's
ok to call it in all cases here.
We were missing error checks at two points. In one case an error return
is meaningful; in another case it is not, as the problem should have
been guarded against at a higher level by emitting far jump islands soon
enough during pasteup of compiled code.
* Simplify the dispatch-to-content region
Simplify the dispatch-to-content region in nsDisplayLayerEventRegions::AddFrame() and AddInactiveScrollPort() if it starts to get large.
* tabs to spaces
- This modifies `loadOneTab` and `addTab` to accept an opener
- This code was adapted from Basilisk's copy of tabbrowser.xml without the refactored code changes (which is a lot more involved as it divides addTab's functions into multiple functions)
This fixes flickering/bars/stripes showing up during quickly-updating
operations on Intel hardware when using XRENDER.

A note about the Scalar Replacement Changes: The M{Load,Store}Unboxed*
instructions in theory could be used to manipulate and analyze typed
arrays. However, TypedArrays should already be excluded from eligibility
because of the potential for cross-thread sharing in a SharedArrayBuffer
world, and so the only support in Scalar Replacement here is for Unboxed
Objects, meaning it can all be removed.
targetFrame is modified during the intersection computation loop, so
it's not the viewport you want if there are scrollframes around.
This bug triggers when IntersectionObservers are used on frames that
wrap.
Follow-up for #249.
