Daniel Dunbar d6fd377f33 Simplify JIT target selection.
- Instead of requiring targets to define a JIT quality match function, we just
   have them specify if they support a JIT.

 - Target selection for the JIT just gets the host triple and looks for the best
   target which matches the triple and has a JIT.
