This will allow us to verify the entire detection pipeline in real nightly
builds, which will give us confidence that real heap corruption will be
detected and reported properly.

ServoStyleSetSizes now has two uses, one for the Stylist, and one for the UA
cache, and so the patch removes 'Stylist' from the field names.

This patch reverts the code changes, but not the test changes from changeset bf9cf6f393eb. There is a crashtest here which is valuable to keep.

This change requires new code to measure HashMaps, which uses the new
'malloc_enclosing_size_of' functions that can measure a heap block from an
interior pointer.
The patch changes MallocSizeOfFn to a newtype, and introduces
MallocEnclosingSizeOfFn alongside.
It also adds new traits: MallocSizeOfBox, MallocSizeOfVec, MallocSizeOfHash.
These each contain a single method that does shallow measurement of the
relevant type, which is often useful. (This is a different style to the
existing MallocSizeOf trait, which does deep measurement, but I'm moving away
from the always-deep-measurement style because it's less flexible.)

The motivation of this patch is that clearing mPresContext should be an
implementation detail of XBL style set, so I create a method for that, and
remove ClearPresContext().

nsDocument::GetAnimationController() will lazily create an animation controller
which, in some call sites, is unnecessary.
This patch first calls HasAnimationController() and only calls
GetAnimationController() if it returns true. This avoids creating an animation
controller in situations where one is not necessarily required.

This patch splits up the existing "layout/style-sets" measurement into
"layout/gecko-style-sets", or "layout/servo-style-sets/stylist/rule-tree" and
"layout/servo-style-sets/other". (Additional things will be measured under
"layout/servo-style-sets/" later, such as cascade data.)
This requires introducing a new type, ServoStyleSetSizes, for transferring the
multiple measurements from Rust code to C++ code.

I've verified with the profiler that we use the parallel traversal for
loading a foreground tab, but not for a tab opened with ctrl-click.

Bindgen bitfield enums don't work as return values with the Linux 32-bit ABI at
the moment because they wrap the value in a struct.
This causes the Rust side to believe the caller will pass along space for the
struct return value, while C++ believes it's just an integer value.

Now that we do process normal traversal even in the case of throttled animation
flush so that we don't need to do special handling for the case.
Note about the comment in has_current_styles():
the remaining animation hints is not caused by either this patch or the
previous patch in this patch series, it's been there in the first place, but
it should be fixed somehow later. See bug 1389675.

The buggy animation handling isn't a regression, since currently we pass
UnstyledChildrenOnly in those cases, which blocks the animation traversal
in Servo_TraverseSubtree.
In general I really wanted to handle these two paths together. But there's
enough broken with the NewChildren path that I wanted to scope the buginess
as tightly as possible. And I really need to separate the handling here from
StyleDocument() to make the restyle root stuff work.

This makes things a bit easier to follow, and sets the stage for eliminating
PrepareAndTraverseSubtree and making StyleDocument restyle-root-aware.
