This case is hit by hovering over menu items, so the optimization is somewhat worthwhile.
As a side-effect, not causing reflows also avoids a XUL <select> popup positioning bug.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

After StyleBasicShape is set to StyleShapeSource, it's life cycle never go
beyond StyleShapeSource, so I make StyleBasicShape hold by a UniquePtr in
StyleShapeSource.
Also, replace all raw pointers to StyleBasicShape by UniquePtr in all APIs.

The original operator==() (implemented by EqualsInternal<true>) is not been
used. Therefore, I expand EqualsInternal<false> into it, and move it to
nsStyleStruct.cpp.
Also, use DefinitelyEqualURIs() in nsStyleStruct.cpp in operator==().

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

This property accepts a color. It's inherited and defaults to transparent.
Its value is respected on macOS when rendering text into transparent pixels.
This property should be used for text that is placed on top of "vibrant"
-moz-appearances, in order to achieve high quality text rendering for such text.
In most cases, the property should be set to a named system color; an upcoming
patch in this patch series will add one such color for each vibrant
-moz-appearance value.
However, in some cases it can also be useful to use a custom color: If text
is rendered into an intermediate surface, for example because a mask is applied
to it, and the background color behind that intermediate surface is known, then
this property can be set to that background color in order to achieve subpixel
AA for the text inside the mask effect. In that case, the font smoothing
background color is respected because text is rendered into transparent pixels
*inside the intermediate surface*. At the moment, the only example of that use
case is the text of the active tab in the state where the text is overflowing.

In Stylo, we read font related user prefs to set the default font size only
if we set 'font-size' property. However, users are allowed to set their
preferred minimum font size through the user prefs, even without using
'font-size' property.
Gecko used to do this in nsRuleNode::SetDefaultOnRoot, which calles the
default constructor of nsStyleFont and does the minimum font size applying
right after. Moving the minimum font size applying into the default
constructor of nsStyleFont shoud be no harm to Gecko, but makes Stylo
share the same code path and behave the same.

If we'll be reconstructing frames for the subtree in question, then we'll also
be reflowing and repainting that whole subtree. So all of this function's
other changehints become unnecessary and redundant.

When the counter style in the style struct changes, CalcDifference
would return ReconstructFrame, which should cause corresponding use
node to be reconstructed. That means a use node with retired counter
style should always be destroyed in the next flush, so it makes no
sense to reset them anymore.
However, we would still need to mark counter lists dirty because
otherwise their content may not get update when there are changes to
counter styles which are still valid.
