	Look at the .gdbint file in the distribution.  It defines a number of useful commands
	for printing trees, RTX's and even chains of INSNS.  It also uses a function that helps
	to locate a particular INSN (by its UID).

	It does seem a good suggestion to document some of this in gccint.info, it was years before I
	knew about the debug_reload() dumping function - and that's incredibly useful for chasing down
	reload problems!
