I just landed the first two patches in
https://bugzilla.mozilla.org/show_bug.cgi?id=809533 on
mozilla-inbound, which makes allocation from nsPresArena and from
the display list arena be infallible. This means that an allocation
failure from one of these arenas will now cause the application to
abort immediately rather than crashing a few lines later due to a
missing null-check. It also means we should remove the null-checks
that we did have (although there are two further patches in that
bug, not yet landed, that do some of this).
