This is useful for writing tests that test particular optimizations,
such as that a particular operation doesn't cause restyles. It sits
next to similar counters for frames constructed and frames reflowed.
I also snuck in a preference for the less-expensive mPresContext over
the more expensive mFrame->PresContext() (which dereferences multiple
pointers).
(Originally written for work I planned to be part of bug 1189598.)

We need to do this because the entire draw region will be added to the layer's
valid region after drawing. If there are parts in the valid region that are not
in the visible region, we still need those parts to have valid content, because
in a later frame the visible region may grow to include those parts.

In the upcoming patch to disable logging, we're going to conditionally
turn MOZ_LOG_TEST into a constant false. But for this instance of
MOZ_LOG_TEST in nsPresContext, turning it into a constant means that
|log| becomes unused. Since |log| isn't used after this point, let's
move the |gfxPlatform::GetLog| call into the MOZ_LOG_TEST call, removing
the temporary variable, and making the compiler happy.
During shutdown, mozilla::services::GetObserverServie will return nullptr. So we should check it. Add another nullptr check

I'm acting under the assumption that this is what's closest to what the
code does now, except without asserting in ~ErrorResult. It also seems
closest to what event listeners will do, both based on examining code
(EventListenerManager::HandleEventSubType, which I'm hoping is the right
code to look at, calls StealNSResult, and then stores it in a member
that's ignored by most callers) and based on testing (for both click
events, and for media query listeners with this patch, the exception
gets reported to the console as an unhandled exception). That said, I'm
not particularly well versed in the current error handling rules so I
may well be off here.
This code should presumably go away when we change this code to use
EventListeners in bug 1265622, so I don't think there's any spec that
covers this.
Without the patch, the mochitest hits the fatal assertion (after
reporting hitting the expected uncaught exception). With the
patch the test passes. (Tested locally.)

Fieldsets break up their border so we need to disable the willPaintBorder optimization for them.

Theoretically we should do the same for nsTreeBodyFrame, but that frame type is
harder to detect and I'm not sure it's worth adding code to support updating
background-position on XUL trees.

It looks like VC++ doesn't like comparisons of nsCOMPtr to 0 after this
change, but those are bad style anyway, so I removed them from
TestCOMPtr.cpp instead of trying to make them work.
Unlike when returning an nsCOMPtr in a ternary operator or passing to a
function, I used .get() here, since the operation is actually unsafe and
deserves to be marked explicitly.
It may be that when the frame is reconstructed after load, the frame gets shorter,
and the old scroll position cannot be restored, because it is out of bounds. In
such a case, we don't want to keep mRestorePos tracking the old scroll position,
because it can get incorrectly applied on a future frame reconstruction. Instead,
for scroll position restorations during frame reconstructions, we just try the
restore once and then clear mRestorePos.
