This patch moves some Chrome mochitests into the plain mochitest
directory, in order to try to preserve the history. It also removes
them from the list of tests. The next patch will fix the tests and
start running them again.

getter_AddRefs for nsCOMPtr does an AssertNoQueryNeeded check when its
temporary is destroyed. For the mReaderThread, this happens at a time when
control of the member variable has been handed over to the reader thread,
which causes a data race in the query needed check when the reader thread
shuts itself down and clears the member.
Switching to RefPtr solves this problem by removing the unnecessary check.

Marionette currently doesn't handle restarts of Firefox that well,
and as such needs a fix on bug 1433873. Sadly this patch cannot be
landed until the mozprocess issues on bug 1433905 have been fixed.
This patch temporarily disables the test for opt/pgo Windows builds
only. Re-enabling is tracked via bug 1495667.

This method does very little, and is called in only a few places, so
just inline it. The error variant is not called at all. Simplifying
this makes it easier for me to change do_QueryInterface.

Move the implementation of the XBL tooltip to C++ so the element can safely
be created during native anonymous content creation. The 'mouseover' and
'mouseout' event handlers were not moved as they appear to be legacy code
that is no longer needed.
A number of tests started perma-failing after this patch. Most failures
were caused by a timing change where plugins sometimes load after the
document "load" event. Many of the failures had intermittents associated
with them and the tests were not waiting for plugins to load before
starting. The test "test_weakmap_keys_preserved2.xul" had a bug where it
was possible for it to finish before all the tests were run.

Some global imports, like `fetch`, expose multiple symbols. This patch

A C++ object that is exposed to JS can have its reflector used as a
key in a weak map. Because a weak map does not keep its keys alive,
this means that the reflector can be discarded if it has no other
references aside from the C++ object, which will in turn remove its
weak map entry. If the C++ object can be accessed again later from JS,
it will get a new reflector which will have no weak map entry. This is
bad because it means some internal implementation detail has resulted
in data loss that is visible to JS. (Side note: this is also an issue
for cross compartment wrappers, which is handled by another
mechanism.)
To fix this, we can preserve the wrapper of any DOM reflector used as
a weak map key. This ensures that the reflector and its C++ object
have the same lifetime. If a WebIDL object is not wrapper cached, that
means that it cannot be accessed via C++, so we don't need to preserve
the wrapper. This is currently implemented for nsISupports classes,
but not other classes. For non-nsISupports classes, it would throw an
error rather than silently fail.
My patch adds support for non-nsISupports cycle collected objects. It
turns out that the existing addProperty hook just does wrapper
preservation, so we just call it for cycle collected classes. This
does mean that if addProperty changes in the future to do something
else, this code will need to be changed.
I verified that this test fails if TryPreserveWrapper is changed to do
nothing besides return true in the non-nsISuports case.

This allows JS callers and C++ callers to both create and consumer iterators
in their preferred style, while still presenting the appropriate interfaces to
callers in the other language.
When a C++ caller requires an nsISimpleEnumerator from an XPCWrappedJS object,
if that class does not already have a QueryInterface method, it is assumed to
be a JS enumerator, and an appropriate wrapper is created. JS callers who wish
to implement nsISimpleEnumerator manually, or opt out of the automatic
conversions, may implement a QueryInterface method, which automatically opts
them out of this behavior.

When an XPC wrapped JS object returns an object from a property or function
which is expected to return a given interface, we create a wrapper for that
interface regardless of whether the object has a QueryInterface method which
claims to support it. For the nsISimpleEnumerator enumerator case, the check
for that existing wrapper comes before the check for the nsISimpleEnumerator
special casing, which breaks automatic conversion in those cases.
This patch moves that check just before the check for the existing wrapper,
and just after the nsIPropertyBag special casing, which has similar semantics.

This moves all the node-specific reporting to nsIDocument.
OrphanReporter delegates all the reporting to that and then returns the sum of
all sizes, which is not ideal but was pre-existing.
Also, I moved the main mStyleSheets size reporting to DocumentOrShadowRoot for
it to be shared between document and ShadowRoot.
I'll add memory reporting for the computed stylesheet maps and such in the
ShadowRoot in a followup.
I went through all the XBL bindings, though it seems I could just use
GetBindingWithContent(), since according to:
