Fix lim. Improve lxl, lxa, lor, str, procs with no locals.
_lim_ must use _loe_ (load word external), not _lde_ (load double-word external). The new patterns for _lxl_, _lxa_, _lor_, _str_ emit shorter code in some cases. The change from GPR_EXPR to REG_EXPR allows moving LXFRAME to a register variable. Add more "reusing" clauses. We have enough registers that ncg almost never reuses a register, but sometimes it can reuse r3. In mach.c, emit one fewer instruction in procedures with no locals.
