Fix the conversion from Perspective into ComputedMatrix.
We convert a perspective function into a ComputedMatrix, but we apply the
perspective length to a wrong matrix item. We should put it into m34,
instead of m43. m43 is for translate parameter Z.

- [X] These changes fix [Bug 1389023](https://bugzilla.mozilla.org/show_bug.cgi?id=1389023).
- [X] These changes do not require tests because we have many transform tests in Gecko already. However, those tests may not be enough, so we should add more in Gecko later.

Now that we do process normal traversal even in the case of throttled animation
flush so that we don't need to do special handling for the case.
Note about the comment in has_current_styles():
the remaining animation hints is not caused by either this patch or the
previous patch in this patch series, it's been there in the first place, but
it should be fixed somehow later. See bug 1389675.
