Summary: Emit the correct .toc psuedo op when we change to the TOC and emit TC entries. Make sure TOC psuedos get the right symbols via overriding getMCSymbolForTOCPseudoMO on AIX. Add a test for TOC assembly writing and update tests to include TOC entries. Also make sure external globals have a csect set and handle external function descriptor (originally authored by Jason Liu) so we can emit TOC entries for them.
