Log:
Fix this test so we don't delete the whole thing.
We compile this loop to amazingly gross code.  What is
wrong with this picture:

entry:
	%tmp2126 = icmp sgt i32 %count, 0		; <i1> [#uses=1]
	br i1 %tmp2126, label %bb.preheader, label %return

bb.preheader:		; preds = %entry
	%tmp = icmp slt i32 %count, 1		; <i1> [#uses=1]
	%smax = select i1 %tmp, i32 1, i32 %count		; <i32> [#uses=1]
	br label %bb
..
