Weiming Zhao 0449d522a6 Folding into CSEL when there is ZEXT between SETCC and ADD
Normally, patterns like (add x, (setcc cc ...)) will be folded into
(csel x, x+1, not cc). However, if there is a ZEXT after SETCC, they
won't be folded. This patch recognizes the ZEXT and allows the
generation of CSINC.

This patch fixes bug 19680.
