* target.def (set_up_by_prologue): New target hook.
* doc/tm.texi.in (TARGET_SET_UP_BY_PROLOGUE): Document it.
* doc/tm.texi: Regenerated.
* function.c (thread_prologue_and_epilogue_insns): Change
set_up_by_prologue HARD_REG_SET into struct hard_reg_set_container.
Call targetm.set_up_by_prologue on it.
* config/rs6000/rs6000.c (rs6000_set_up_by_prologue): New function.
(TARGET_SET_UP_BY_PROLOGUE): Redefine to it.
