Add pnacl-freeze to the tests_lit/lit.cfg. Also, unsigned vs signed.

Add pnacl-freeze to the tests_lit/lit.cfg. Also, unsigned vs signed.

Otherwise, I don't have pnacl-freeze in my path, and
I think the lit tests have trouble finding it.

LGTM.

Now that the build system has the Subzero directory next to llvm, I'm (for other
reasons) looking into a better PATH setup, which could fix the pnacl-freeze
issue.
