Basically, the easiest way to describe the effect of this change is "float placement takes line height into account". It didn't before, which could lead to lines overlapping floats or floats taking up too much vertical space.

As the float ceiling is relative to the border box, not the margin box,
of the parent flow, top margin must not be included.
This exposed a pre-existing bug whereby margins are discarded if a block
contains only floats and no content, affecting the tests
`float_intrinsic_height.html` and `margins_inside_floats_a.html`. As a
workaround, some invisible content has been added to the bodies of both
tests.

As far as I can tell, this is a cut-and-paste of old buggy code from
block flows. Delegating to the correct block flow code fixes the sidebar
float placement on Guardians of the Galaxy.

The speculated inline-size of the preceding floats was forced to zero at
the wrong time if the float was itself cleared, causing it to overwrite
the speculated value. Shuffling the code around a bit fixes the problem.

There are several optimizations here:
* We make font families atoms, to allow for quicker comparisons.
* We precalculate an FNV hash of the relevant fields of the font style
structure.
* When obtaining a platform font group, we first check pointer equality
for the font style. If there's no match, we go to the FNV hash. Only
if both caches miss do we construct and cache a font group. Note that
individual fonts are *also* cached; thus there are two layers of
caching here.

Transition events are not yet supported, and the only animatable
properties are `top`, `right`, `bottom`, and `left`. However, all other
features of transitions are supported. There are no automated tests at
present because I'm not sure how best to test it, but three manual tests
are included.

- Most of util::memory has been moved into profile::mem, though the
`SizeOf` trait and related things remain in util::memory. The
`SystemMemoryReporter` code is now in a submodule
profile::mem::system_reporter.

This fixes a bug in finding the top left corner of an RTL block in physical coordinates. (The old code used the `start` point of the `position` rect, which is not always the top left.)
It also fixes the setting of `position.start.i` in certain mixed LTR/RTL cases.
There is still a bug related to `position.size` for RTL blocks with margins. See the FIXME comments for details.

Cycles were being created in the flow tree since absolutely positioned
descendants had pointers to their containing blocks. This adds
WeakFlowRef (based on Weak<T>) and makes these backpointers weak
references. This also harmonizes our custom Arc<T>, FlowRef, to be
consistent with the upstream implementation.
Fixes#4915.

When a viewport is resized, the computed values for a style containing viewport percentage length units become stale. However, there's no way for those styles to be invalidated after a resize. As a solution, this commit invalidates the computed values cache after a resize has occurred, which is probably over-kill.
A better solution would probably be to track under what conditions computed values remain valid, and invalidate them as indicated.

Only simple alphabetic and numeric counter styles are supported. (This
is most of them though.)
Although this PR adds a sequential pass to layout, I verified that on
pages that contain a reasonable number of ordered lists (Reddit
`/r/rust`), the time spent in generated content resolution is dwarfed by
the time spent in the parallelizable parts of layout. So I don't expect
this to negatively affect our parallelism expect perhaps in pathological
cases.

...and vice-versa. This is not a complete fix for all mixed-direction layout cases, but it fixes enough problems to make some simple test cases pass, like tha attached reftest.
There are FIXME comments for many of the remaining issues. In particular, this does not yet handle RTL layout of fixed/absolute elements, nor does it completely fix the overconstrained_block reftest.
