"-mllvm -print-after-all" is what you're looking for, although this
will cause it to print out the bitcode between *every* pass being
executed, including those added by safecode.

(There's also "-mllvm -print-after" and "-mllvm -print-before" that
take lists of passes, but I don't know how they work and would
requiring enumerating all the passes anyway).

Unfortunately on my build this causes safecode's clang to crash (but
this doesn't happen on my builds of clang-3.0 and clang-3.1).  Not
sure what's happening there, but perhaps it will work for you.
