Original issue's description:
> Fix NVPR assert for equivalent ovals
>
> For oval paths, GrPath ignores the point order and only uses the bounds
> when building its key.  This is problematic because
>
> 1) point order is important when dashing
> 2) GrStencilAndCoverPathRenderer asserts that the lookup SkPath is equal
>    to the cached SkPath - which is not the case for ovals with different
>    directions/different point order.
>
> With this CL we no longer use the reduced oval key when dashing, and
> instead fall through to the more general path cases.  The assert is
> adjusted to accommodate "equivalent" ovals (when not dashing).
>
> Also re-enabled & updated the GpuDrawPath unit test (disabled in
> https://codereview.chromium.org/1456463003/, presumably due to the use
> of uninitialized SkRects).
