[Bug rtl-optimization/20070] If-conversion can't match equivalent code, and cross-jumping only works for literal matches

I am testing Steven's Crossjumping patch attached here. With CoreMark we see a
1% increase in performance when using Os. Other proprietary tests show ~0.5%
decrease in code size.

The path however does not fix PR30905.
