nsTArray::AppendElement{,s} uses an IncrementLength method to adjust the
length of the array after appending elements. There are checks in
IncrementLength to ensure that we're not incrementing the length stored
in the static empty header object; these checks are necessary in cases
such as appending a zero-length array to another zero-length array.
But we do not need this check when we're calling AppendElement: we know
the header is obviously not the empty header, because we increased the
length of the array by one for the newly appended element. Incrementing
the length can therefore be inlined, saving ~90K of codesize on x86-64
Linux.
