SIL: Give Unreachable instructions SILLocation info. UnreachableInst's constructor didn't take a SILLocation. Oops. Fix that, and associate Unreachables emitted due to failed switch coverage with the switch. For missing-return Unreachables, there isn't yet readily available SILLocation info to attach to them, but Anna will fix that soon. Swift SVN r6132
