regclass.c (record_reg_classes): '?' increases cost by two.
* regclass.c (record_reg_classes): '?' increases cost by two.
* reload.c (find_reloads): Double previous costs. Output
reloads cost one unit extra.
* reload1.c (eliminate_regs): Delete LOAD_EXTENDED_OP code that
boiled down to && ! 0.
* reload.c (find_equiv_reg): Also consider a goal offset from the
frame pointer to be constant.
