Include a stack trace in the panic message, when GHC is compiled
profiled.
I tried this out on the panic we're currently getting for #3103:
ghc-stage2: panic! (the 'impossible' happened)
(GHC version 7.3.20111128 for x86_64-unknown-linux):
tcIfaceGlobal (local): not found:
base:GHC.Word.W#{d 6w}

(r6P, Identifier `base:GHC.Word.$fEqWord{v r6P}'),
(r6Q, Identifier `base:GHC.Word.$fNumWord1{v r6Q}'),
