bfin.c (struct machine_function): New member has_loopreg_clobber.
* config/bfin/bfin.c (struct machine_function): New member
has_loopreg_clobber.
(bfin_expand_movmem): Set it when generating memcpy insns.
(n_regs_saved_by_prologue, expand_prologue_reg_save,
expand_epilogue_reg_restore): If we have hardware loops,
memcpy insns (indicated by has_loopreg_clobber) or function
calls, we need to save the loop registers.
