commit-bot@chromium.org 88c3e279ab Refactor SkRecord opts, converting playback optimizations where possible.
This adds back two optimizations from SkPicture: drawPosText strength reduction to drawPosTextH, and pointless save-foo-restore blocks are noop'd away.

The small-T optimization in SkRecord gets in the way of implementing replace(), so I removed it.

Just to keep the API focused, I removed the methods on SkRecord that iterate over i for you; it's just as efficient to do it yourself, and all of the interesting code does its own custom iteration.
