Mike Klein 024072af62 Reland "Improve degenerate 2pt conical gradient cases" 
This reverts commit 95af4726bf.

Reason for revert: I think this may not have been the reason the Android roll was failing.  We've rolled, so it's a good time to try again.

> > The change caused blink layout tests when encountering very small or zero radii. The original patch switched the order of checking if the radii are equal and if the start radius was 0. In the case where both radii are 0, the original code created an actual radial gradient of radius 0 and the new code rejected the shader. A radial gradient with radius of 0 properly renders the last border color as a fill.
> > 
> > This made me realize that the case when the center positions and the radii are the same can be handled more correctly than just always returning an empty shader, so the fix now applies simplifications to the gradient definition depending on the tile mode and should not trigger any blink tests. I added a row to the gradient edge cases GM to make sure it degrades gracefully.
