Log Message:
- Clean up ddb_trap() somewhat, and handle exceptions that happen while we're
in DDB (e.g. if a bad pointer was dereferenced; the debugger will recover).
- Change a comment to indicate that we are on the debugger stack when we get
to ddb_trap().
- Fix possible buglet in computation of the branch target in db_branch_taken().
