* rtl.texi (RTX_FRAME_RELATED_P): Add documentation.
* rtl.h (struct rtx_def): Update comment for frame_related field.
(set_unique_reg_note): Declare prototype.
* dwarf2out.c (dwarf2out_frame_debug_expr): Split out from
'dwarf2out_frame_debug' to handle only expressions, and process
component parts of a PARALLEL expression.
(dwarf2out_frame_debug): Process insns only, and call
new function 'dwarf2out_frame_debug_expr' for patterns.
* emit-rtl.c (set_unique_reg_note): New function to add a reg note,
but if there is an existingone, deletes it first.
* expmed.c (expand_mult, expand_divmod): Use set_unique_reg_note.
* optabs.c (add_equal_note, expand_binop): Use set_unique_reg_note.
(emit_no_conflict_block, emit_libcall_block): Use set_unique_reg_note.
(expand_fix): Use set_unique_reg_note.
