Another step towards getting rid of dependencies to the legacy pass manager. Primary change here is to just do -passes=foo instead of -foo in simple situations (when running a single transform pass). But also updated a few test running multiple passes. Also removed some "duplicated" RUN lines in a few tests that where using both -foo and -passes=foo syntax. No need to do the same kind of testing twice.
