rs6000: Move rs6000_vect_nonmem into target cost_data
This patch is to move rs6000_vect_nonmem (target cost_data
related information) into target cost_data struct.
As Richi pointed out, we can gather data from add_stmt_cost
invocations. This is one pre-step to centralize target
cost_data related stuffs.
gcc/ChangeLog:
* config/rs6000/rs6000.c (rs6000_vect_nonmem): Renamed to
vect_nonmem and moved into...
(struct rs6000_cost_data): ...here.
(rs6000_init_cost): Use vect_nonmem of cost_data instead.
(rs6000_add_stmt_cost): Likewise.
(rs6000_finish_cost): Likewise.
