[PATCH, committed] Fix three comments


Committed as obvious.

Paolo

2004-03-01  Paolo Bonzini  <bonzini@gnu.org>

	* combine.c (try_combine):  Do not refer to is_replaced.
	(gen_lowpart_for_combine):  Perverse subregs now have a
	more politically correct name.
	* cse.c (cse_insn): Likewise.
	* jump.c: Fix bogus reference to delete_insn.
