Caused by:

* config/rs6000/altivec.md: Add new patterns for calls to
save_world/rest_world functions.
* config/rs6000/rs6000-protos.h: (save_world_operation,
restore_world_operation) new declarations.
* config/rs6000/rs6000.c: (struct rs6000_stack) new world_save_p
field added.
(rs6000_stack_info): Set world_save_p field.
(save_world_operation): New function.
(restore_world_operation): New function.
(compute_save_world_info): New function.
(rs6000_stack_info): Call compute_save_world_info.
(rs6000_emit_prologue): Check for world_save_p and generate
pattern to call save_world for saving all non-volatile and
special registers.
(rs6000_emit_epilogue): Check for world_save_p and generate
pattern to call rest_world to restore saved registers.
config/rs6000/rs6000.h: macros FIRST_SAVED_ALTIVEC_REGNO,
FIRST_SAVED_FP_REGNO, FIRST_SAVED_GP_REGNO defined.
(rs6000_reg_names): New entries added for save_world_operation and
restore_world_operation.
Which makes this a regression.
