rtl-ssa: Add debug routines for def_splay_tree

This patch adds debug routines for def_splay_tree, which I found
useful while debugging PR116009.

gcc/
	* rtl-ssa/accesses.h (rtl_ssa::pp_def_splay_tree): Declare.
	(dump, debug): Add overloads for def_splay_tree.
	* rtl-ssa/accesses.cc (rtl_ssa::pp_def_splay_tree): New function.
	(dump, debug): Add overloads for def_splay_tree.
