Skip tests that are expected to fail in both Stylo and Gecko modes. They would unexpectedly "pass" in styloVsGecko mode when comparing the two failures, which is not a useful result.

Disable 461917-1.xhtml under dom/xul/crashtests/ because I cannot reproduce
it locally.
Annotate assert-if on some crashtests (bug 1370830). Other modifications are
all removal of fails-if.

Test 1322843-1[a-d] fail before part 2, while the other two tests fail

In nsBlockFrame::PlaceLine(), we query the float available space by
using the line's BSize(), which may cause the line to reflow again due
to available space shrunk.
The first issue lies in the second reflow. That is, we do not leverage
the line's BSize() computed in the first reflow to query the float
available space when updating the inline reflow engine in
BlockReflowInput::AddFloat(). So some tall inline elements could still
overlap the floats as in the first reflow.
To solve this, we cache current line's BSize so that it could be
used to update the inline reflow engine when redo the line.
Another issue is in nsBlockFrame::PlaceLine(). When determined whether
the available space is shrunk, we use the float manager's state *before*
placing the line. So if current line has floats, they're not considered.
To solve this, we use the current set of floats to get the float available
space for comparison, and leave the original aFloatAvailableSpace to provide
the information when redoing the line.

What's happening here is that we enter an infinite loop by oscillating
between two states. The code assumes that (a) the available space will
never grow, only stay the same or shrink, and (b) that we should break
out of the loop if it stays the same. This also means we hit the
assertion about the available space growing every other time through the
loop.
This is in the inner loop in nsBlockFrame::ReflowBlockFrame that was
introduced in https://hg.mozilla.org/mozilla-central/rev/80ef9bb2c2e9 .
The problem is fundamentally a logic error in that code. The makes the
assumption that if you reduce the width available to a block formatting
context or replaced block-level element, its height does not shrink.
(The "replaced block" (really block formatting context) in this case, as
in the original testcase, is a scroll frame. I didn't debug the
original testcase enough to figure out what caused its sizing
characteristics, although a percentage-width image does seem like the
most likely candidate.)
Without the patch, the reftest test (but not reference) hangs, as does
the semi-simplified test in the bug (given a narrow window).
With the patch, neither the semi-simplified test in the bug nor the
reference hangs, and the reftest passes.

The change to the 427129-table-caption test was just to make the
reference match the test.
The change to the other 427129 tests was duplicating the test that
failed, adjusting the reference for one version of it (no longer pushed
down), and testing an alternative pushed-down case for the other
version.
It's not clear to me how to test that that
1062963-floatmanager-reflow.html still tests what it originally tested,
given the code change that's happened since.

This adds an additional retry loop in block reflow that we can only
trigger when reflowing a block formatting context (replacedBlock
non-null). It can retry in two different ways, either with a narrower
width but at the same vertical position (when
ReplacedBlockFitsInAvailSpace is still true) or at a new vertical
position (which is treated as a form of clearance).
Fortunately we don't have to worry about margins collapsing *through*
such a boundary since we're dealing with a new block formatting context.
Note that Chromium passes all of the new bfc-displace-* tests, although
it moves the block formating context down unnecessarily in
bfc-shrink-1.html (which we do neither before nor after the patch),
though agrees with the width we have after the patch (but not before the
patch).
