Summary: Extend analysis forwarding loads from preceeding stores to work with extended loads and truncated stores to the same address so long as the load is fully subsumed by the store. Hexagon's swp-epilog-phis.ll and swp-memrefs-epilog1.ll test are deleted as they've no longer seem to be relevant.
