Revert of Picture Recording: fix the performance bottleneck in SkDeferredCanvas::isFullFrame

Revert of Picture Recording: fix the performance bottleneck in SkDeferredCanvas::isFullFrame (patchset #7 id:140001 of https://codereview.chromium.org/545813002/)

Reason for revert:
This is leaking memory:

Original issue's description:
> Picture Recording: fix the performance bottleneck in SkDeferredCanvas::isFullFrame
> 
> blink skips all pending commands during picture recording if it is drawing an opaque full-frame 
> geometry or image. This may improve performance for some edge cases. To recognize an opaque 
> full-frame drawing should be cheap enough. Otherwise, the overhead will offset the improvement. 
> Unfortunately, data from perf for content_shell on Nexus7 shows that SkDeferredCanvas::isFullFrame 
> is far from cheap. Table below shows that how much isFullFrame() costs in the whole render process.
> 
> benchmark                              percentage 
> my local benchmark(draw 1000 sprites)   4.1%
> speedReading                            2.8%

> By contrast, real recording (SkGPipeCanvas::drawBitmapRectToRect) and real rasterization 
> (GrDrawTarget::drawRect) cost ~4% and ~6% in the whole render process respectively. Apparently, 
> SkDeferredCanvas::isFullFrame() is nontrivial.

> telemetry smoothness canvas_tough_test didn't show obvious improvement or regression.
