Log message:
* config/m68hc11/m68hc11.c (m6812_cost): Make cost of add higher
than a shift to avoid adding a register with itself.
(m68hc11_memory_move_cost): Take into account NO_REGS.
(m68hc11_register_move_cost): Update and use memory move cost
for soft registers.
(m68hc11_address_cost): Make cost of valid offset not 0 so that
it gives more opportunities to cse to optimize.
* config/m68hc11/m68hc11.h (REGISTER_MOVE_COST): Pass the mode.
* config/m68hc11/m68hc11-protos.h (m68hc11_register_move_cost): Update.
