V_SAVE_INLINE, SAVRES_LR, SAVRES_SAVE, SAVRES_REG,
SAVRES_GPR, SAVRES_FPR, SAVRES_VR): Define.
(no_global_regs_above): Delete.
(no_global_regs): New function.
(rs6000_savres_strategy): Handle vector regs. Use proper lr_save_p
value for load multiple test.
(savres_routine_syms): Increase size.
(rs6000_savres_routine_name, rs6000_savres_routine_sym,
ptr_regno_for_savres, rs6000_emit_savres_rtx): Pass in int selector
rather than a number of boolean flags. Update all callers.
(rs6000_savres_routine_name): Generate vector save/restore names.
(rs6000_savres_routine_sym): Handle vector regs. Delete forward decl.
(ptr_regno_for_savres, rs6000_emit_savres_rtx): Likewise.
(rs6000_emit_prologue): Delete saving_FPRs_inline, saving_GPRs_inline
and using_store_multiple. Expand uses. Don't always use r11 as
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
reg setup for out-of-line fp save. Emit call to out-of-line vector
save function. Choose r11 or r12 for vrsave reg when available for
better scheduling.
(rs6000_output_function_prologue): Don't emit .extern for ELF.
(rs6000_emit_epilogue): Choose a better frame reg when restoring
from back-chain to suit out-of-line vector restore functions. Emit
call to out-of-line vector restore function. Adjust register used
for cr restore. Tweak pointer register setup for gpr restore.
* config/rs6000/rs6000.h (FIRST_SAVED_GP_REGNO): Take into account
FIXED_R13.
* config/rs6000/sysv4.h (FP_SAVE_INLINE, GP_SAVE_INLINE): Simplify.
(V_SAVE_INLINE): Define.
* config/rs6000/altivec.md (save_vregs_*, restore_vregs_*): New insns.

* config/rs6000/crtsavevr.S: New file.
* config/rs6000/crtrestvr.S: New file.
* config/rs6000/t-savresfgpr: Build the above.
* config/rs6000/t-netbsd: Likewise.
