libxml 2.9.0 (we updated from 2.7.x to 2.9.2 for M45) added a
default-on abort on > 10,000,000 byte documents which is a bit
arbitrary and is causing problems for users. The _HUGE option
makes it not do this. My assumption is that this is reasonable
behaviour security-wise as: 1) we were doing it this way until
recently; and 2) it shouldn't be any worse in the renderer than
just doing `for (;;) x+='y';`

(There's a big trivial xml file in
LayoutTests/http/tests/xmlhttprequest/resources/big.xml
that goes with the test, but git cl upload won't upload it. I
guess I'll dcommit just that file first?)
