Really sorry for the size of the patch :(
Only intentional behavior change is in the uses of HasLengthAndPercentage(),
where it's easier to do the right thing. The checks that used to check for
(IsCalcUnit() && CalcHasPercentage()) are wrong since bug 957915.

If we're waiting on an interrupt, then our child items haven't been totally
reflowed and our measures would be bogus.
This will probably regress performance in the cases bug 1209697 fixed, so we
should probably add an interrupt check somewhere in nsFlexContainerFrame to
avoid keeping reflowing flex containers indefinitely.
We could probably just bail out from our reflow if any kid reflow was
interrupted.
Filed bug 1495532 to consider that.

Assuming we call MarkIntrinsicISizesDirty in the appropriate scenarios, this
patch shouldn't change behavior - it just caches these values so we don't
needlessly recalculate them.

This patch does not change behavior; it just merges the implementations of
these two functions into a single common function.

This patch doesn't change behavior.
It simply makes us share code/data for two different cases that both ended up
producing mainAxisCoord->GetUnit() == eStyleUnit_Auto. Now, they'll *both* use
the same static nsStyleCoord to represent this "auto" value.
Originally, in one of these cases ("flex-basis:auto;[main-size-property]:auto),
we left the mainAxisCoord untouched. Now we'll point it at this dummy 'auto'
value. Either way we end up with mainAxisCoord->GetUnit() == eStyleUnit_Auto,
so the behavior doesn't change.
The next patch in this series will make further changes to one of these spots,
as noted in the "XXXdholbert" code-comment included here.

This patch doesn't affect behavior - it's just refactoring / de-duplicating.
(The refactored function does include some new "legacy box" code, just for
completeness & to ensure that the included assertion passes. But beyond the
assertion, that new code isn't exercised right now -- this function's only
callsites are skipped if the NS_STATE_FLEX_IS_EMULATING_LEGACY_BOX state-bit is
set on the container. Hence, this patch still doesn't affect behavior, even
though it's adding some new logic in the refactored-out function.)

In particlar, this patch:
- ...renames a bunch of 'auto'-BSize-measurement functions/variables from
"Height" to "BSize". (I thought about splitting this part out, but
typically the correctness of the renames was intrinsically tied to the logic
generalizations that I'm performing here, and vice versa, so it seemed
clearest to group it all together.)
- ...replaces some calls to IsMainAxisHorizontal() with the more general
"FlexItem::IsInlineAxisMainAxis()" API, for cases when we're reasoning about
whether a flex item's main-size is really just its (easier-to-resolve) ISize.
- ...replaces some calls to IsCrossAxisHorizontal() with either
IsColumnOriented() or FlexItem::IsInlineAxisCrossAxis() (depending on
whether we're reasoning about the flex container's cross-size vs. a flex
item's cross size).
This makes a bunch of tests start passing (including a "received" w3c
reftest/wpt-test), so this patch also removes some failure annotations.

In modern flexbox and in "display:-webkit-box", children with
"visibility:collapse" currently generate "struts" which have 0 main-size but
nonzero cross-size.
But XUL/-moz-box treats these children differently -- it makes them 0-sized in
both axes. So we need to add a custom behavior to modern flexbox in order to
emulate that.
Specifically, this patch makes us:
- Ignore these children when computing the flex container's intrinsic sizes.
- Take a simpler codepath with 0-sized struts for collapsed elements when
laying out a -moz-box (rather than the typical 2-pass layout, with strut
cross-size being established in the 1st pass).

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

We have a fair number of files that have a particular stale version of the MPL
boilerplate. (It was probably originally correct, and then the official
boilerplate changed, and the stale MPL boilerplate continued to propagate via
copypasting from neighboring files into newly-added files.)
This patch updates this stale MPL text (and *only* the MPL text) to the latest
version, which can be found at https://www.mozilla.org/en-US/MPL/headers/ and
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line

nsIFrame::mClass is of type enum class nsQueryFrame::ClassID which is
a strict subset of the nsQueryFrame::FrameIID values. For a concrete
frame class, its FrameIID is the same numeric value as its ClassID.

For some stretched items, we override the computed height of the input for
measuring reflows, which may change the ascent and height result.
Just use that as a key for the reflow result cache too.

Note that at the callsites in nsCSSFrameConstructor.cpp, we have to also check
the frame type (since the frame state bit is in a range of bits whose meaning
differs depending on frame type). The first change in this patch is the
addition of a convenience fucntion that checks both the frame type as well as
the frame state bit.
