DWARF2 frame notes for hppa.
* dwarf2out.c (dwarf2out_frame_debug_expr): Support adjusting
stack pointer via a LO_SUM. Ditto for setting a temp register
used to save to the stack. Set cfa_temp when setting fp, and
allow matches to cfa_temp in addition to cfa_store when saving
regs. Handle POST_INC and LO_SUM register stores. Document the
changes and errors in rule 12 doco.
* pa.c (set_reg_plus_d, store_reg, load_reg): Return last insn.
(actual_fsize, local_fsize, save_fregs): Move for store_reg to see.
(load_reg): Move closer to epilogue code.
(DO_FRAME_NOTES): Define to control the following..
(FRP): Define to set RTX_FRAME_RELATED_P on insns.
(hppa_expand_prologue): Use FRP and REG_FRAME_RELATED_EXPR
notes as necessary.
(hppa_expand_epilogue): Likewise.
