(rs6000_savres_routine_name, rs6000_savres_routine_sym,

rather than a number of boolean flags. Update all callers.

(rs6000_emit_prologue): Delete saving_FPRs_inline, saving_GPRs_inline

frame reg when needed for out-of-line saves. Set up initial offset
for out-of-line vector saves when buying stack frame. Handle pointer

save function. Choose r11 or r12 for vrsave reg when available for

call to out-of-line vector restore function. Adjust register used
for cr restore. Tweak pointer register setup for gpr restore.
