Part 5 of a long series filed on behalf of Austin English. (I hope you're not
tired of me at this point...)

Clang is also miscompiling the Dialog Manager code (dlls/user32/dialog.c) from
Wine. This one's weird. It's not crashing, but it locks up and produces no
output whatsoever. Valgrind reports an invalid 4-byte read inside the Dialog
Manager, so this might have something to do with it. Not sure if it's optimizer
related, but it's probably not integrated-assembler-related.
