I was wrong.  The actual patch that introduced the regression was installed
a little latter in the day:

2003-12-05  Roger Sayle  <roger@eyesopen.com>

	* dojump.c (do_jump): If the expression being compared against
	zero, is the subreg of a promoted variable, perform the comparison
	in the promoted mode.
	* simplify-rtx.c (simplify_unary_operation): Optimize sign and
	zero-extensions of subregs of promoted variables where the
	extension is identical to that used to promote the variable.

Dave
