Revert "Turn off extern templates for most uses."

Turning off explicit template instantiation leads to a pretty
significant build time and code size cost. We're better off dealing
with ABI incompatibility issues that come up in a less heavy handed
way.

This reverts commit r189610.

Get testsuite running on FreeBSD.

Add initial support for using LIT to run the tests on FreeBSD. 
More work may need to be done to add support for FreeBSD but this is a
good initial step.

Readding FreeBSD support to lit.cfg. Patch from Pawel Worach.

Pawel has been using this patch on his buildbots for a while. This should
allow the testsuite to run on FreeBSD with libcxxrt.
