elk/cmod: Don't propagate from CMP to ADD if there is a write between
If either source of the CMP is modified before an appropriate ADD is
found, the ADD and the CMP will not have the same result.

No shader-db changes on any ELK platform. I suspect the problematic
cases only occur after scheduling has rearranged instructions. This is
likely the reason BRW didn't experience this problem until 09450faf.
