[cfe-commits] missing includes for several tests

[Jonathan Gray]

These tests fail due to missing types without the following
includes, on OpenBSD and likely other systems.

The dragonfly/freebsd tests also fail unless something
like what is described in
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20090629/018744.html
is done.
