Fix -ftrap-function fallout from llvm r145714. <rdar://problem/10799325>

That llvm change removed the -trap-func backend option, so that using
-ftrap-function with clang would cause the backend to complain.  Fix it
by adding the trap function name to the CodeGenOptions and passing it through
to the TargetOptions.
