GrTessellator: fix for collinear edge merging.

In some cases, two edges can be collinear when tested on one side
(e.g., left top vs right edge), but non-collinear when tested on the
other (e.g., right top vs left edge). We were actually merging based
on one criterion, but assserting based on the other.

The safest fix is to merge if either condition is true, and then
assert that both conditions are false.
