Bug 1778463: Firefox is pinned to the taskbar even though the "On my taskbar" checkbox is unchecked r=mhowell

The problem here ended up being that we lose the value of `AddTaskBarSC` once ExecCodeSegement is called -- which we do anytime we try to set ourselves as the default if the installer was run elevated.

For the print preview documents, they are cloned from the original document in
Document::CreateStaticClone[1]. But the cloned document isn't attched to any
nsIContentViewer yet so it won't have any global object. The document is
attached to the nsIContentViewer later when the cloning is done[2].

Also, the script elements from the cloned document are also cloned from
the original document, so they won't be processed in the cloned document.

Therefore we simply bail out if the module loader isn't initialized yet.

Since https://github.com/w3c/FileAPI/issues/43 is still open, it is unclear how body.type should work.
The current wpts expect some behavior which isn't in the specifications.
So, since the situation is very messy in the specifications, the patch is doing a
spot fix for boundary handling. It is ugly, but shouldn't change other behavior.

Bug 1778091 - Make `HTMLEditor` move invisible `<br>` element into the empty inline element after splitting a paragraph at end r=m_kato

In Yahoo! Mail, the paragraph has `<br>` after `<span>` element which has
`background-color`.  In this case, Gecko creates the following DOM tree after
splitting the paragraph:
```
<div><span>foo</span></div><div><span></span><br></div>
```
Then, the empty `<span>` in the right paragraph will be removed by the
post-processing.  However, in this case, the inline element is required for
preserving the style continued from the previous paragraph.

In this case, we should move the `<br>` element into the `<span>` to make
it non-empty and avoid it to be removed.  This is compatible with Chrome.

When reading Dwarf unwind info, `CallFrameInfo::State::DoInstruction` is
called once per CFI instruction.  At both call sites, the call is driven by a
simple loop.  Because each call doesn't do much work, the call overhead is
quite high, and there are huge numbers of CFI instructions to be processed.

This patch moves the loop into its own method `DoInstructions`, and adds
annotations in the hope of getting `DoInstruction` inlined into the loop.

On an Intel Core i5 1135G7 at circa 4 GHz, this reduces the Dwarf read time
from 0.27 seconds (after bugs 1754932, 1777540 and 1777949 have landed) to
0.26 seconds.  Not much of a win, but on the other hand, the insn count falls
from 3906 million to 3640 million, which seems like a worthwhile win for what
is a trivial change.

Backed out changeset 457c6c1a18e3 (bug 1763570) for causing layout/forms/test/test_bug644542.html CLOSED TREE

When setting focus to input element, Gecko sets focused element to central via
`zoomToFocusedInput`. So when we receives `focusin` event, content may be
scrolled and zoomed. To pass correct element rectangle, we have to wait until
it is completed.

Fennec added `PanZoom:StateChange` event to listen APZ state. So GV should use
same way.
