Change SkImageFilter's cropRect from SkIRect to a CropRect struct, containing an SkRect and flags indicating which parameters are set.

NOTE: this will require SK_CROP_RECT_IS_INT=1 to be set in Chrome until Blink has been updated to use SkImageFilter::CropRect. Include https://codereview.chromium.org/26528002/ with the Skia roll.

Note also that SK_CROP_RECT_IS_INT is a temporary measure until all call sites in Blink have been updated to use SkRect.
