Revert of Begin instanced rendering for simple shapes (patchset #20 id:380001 of https://codereview.chromium.org/2066993003/ )

Reason for revert:
This caused static initializer regressions in Chromium (crbug.com/625728).

Original issue's description:
> Begin instanced rendering for simple shapes
>
> Adds a module that performs instanced rendering and starts using it
> for a select subset of draws on Mac GL platforms. The instance
> processor can currently handle rects, ovals, round rects, and double
> round rects. It can generalize shapes as round rects in order to
> improve batching. The instance processor also employs new drawing
> algorithms, irrespective of instanced rendering, that improve GPU-side
> performance (e.g. sample mask, different triangle layouts, etc.).
>
> This change only scratches the surface of instanced rendering. The
> majority of draws still only have one instance. Future work may
> include:
>
>  * Passing coord transforms through the texel buffer.
>  * Sending FP uniforms through instanced vertex attribs.
>  * Using instanced rendering for more draws (stencil writes,
>    drawAtlas, etc.).
>  * Adding more shapes to the instance processor’s repertoire.
>  * Batching draws that have mismatched scissors (analyzing draw
>    bounds, inserting clip planes, etc.).
>  * Bindless textures.
>  * Uber shaders.
