Remove the bogus rules for 'lor 2' and 'str 2'.

Browse source 
These instructions would load or store the EM heap pointer.  They
don't work.  Programs must use brk() or sbrk() in libsys.

The last file to use 'lor 2' and 'str 2' was lang/pc/libpc/sav.e in
the Pascal library.  Commit c084f9f deleted the file, so we no longer
need rules 'lor 2' or 'str 2' to build the ACK.
