Avoid a panic when handling collapsing borders (fixes#7144)
There is no need to compute next_collapsed_borders_in_block_direction for all kind of flows when it's used only in the table row case. That also avoids a panic when the next child is a table colgroup (this should not happen when iterating over a table row).

layout: Improve our handling of inline absolute containing blocks.
Several issues are addressed in this commit:
* Inline flows now bubble up their absolute descendants instead of
making the inline flow the containing block for them. (In the future,
we will need to make the inline flow *sometimes* be the containing
block for them, but for now it improves sites to unconditionally
bubble up.)
* Fragments now look at their inline fragment context to determine
whether they are positioned.
* Inline flows now push the stacking-relative position of the absolute
containing block down to their inline-block fragments.
* Inline absolute hypothetical fragments can be containing blocks.
* Fixes the logic in
`containing_block_range_for_flow_surrounding_fragment_at_index`. The
condition to determine whether fragments are positioned was inverted!
* `Descendants`/`AbsDescendants` has been refactored in order to become
more friendly to inline absolute containing blocks in the future.
Improves the inline position of the green drop-down arrow in the Google
SERPs. (The block position is still wrong.)

This is necessary for the devtools "Start Recording Performance" button to
send a message.
(This message is not yet supported, so it leads to
'unexpected message type "startRecording" found for actor "performance4"'.)
Upgrade Rust to nightly 2015-08-10
Still needs snapshot.
Snapshot probably could also work as today's nightly (I wasn't able to download the latest one due to choppy internet), there isn't any plugins churn I know of

Fix "'PaintWorker' panicked at 'index 0 and/or 4 in `*` do not lie on…
… character boundary" when printing display list.
This whole piece of code seems a bit fragile, but it fixes the immediate problem for now.
