All the tests that say "No available targets" are incorrectly
configured; they assume the x86 backend is available.  They can be
"fixed" easily, but that won't really get you closer to a usable
compiler.

I would guess that all the PCH tests are crashing for the same reason,
so fixing that could fix a lot of failures at once on the clang side.

If you're interested in actually having a usable compiler for your
system, I would say the crashes in CodeGen/Generic and CodeGen/PowerPC
are the highest priority.
