Register assembly printer passes in the pass registry. This makes it possible to use `llc -start-before=<target>-asm-printer ...` in tests. Adds a `char &ID` parameter to the AssemblyPrinter constructor to allow targets to use the `INITIALIZE_PASS` macros and register the pass in the pass registry. This currently has a default parameter so it won't break any targets that have not been updated.
