Optimized implementation of quickReject()

Impl Overview
(1) Keep the device clip bounds up to date.  This
    requires minimal additional work in a few places
    throughout canvas.
(2) Keep track of if the ctm isScaleTranslate.  Yes,
    there's a function that does this, but it's slow
    to call.
(3) Perform the src->device transform in quick reject,
    then check intersection/nan.

Other Notes:
(1) NaN and intersection checks are performed
    simultaneously.
(2) We no longer quick reject infinity.
(3) Affine and perspective are both handled in the slow
    case.
(4) SkRasterClip::isEmpty() is handled by the intersection
    check.

Performance on Nexus 6P:
93.2ms -> 59.8ms

Overall Android Jank Tests Performance Impact:
Should gain us a ms or two on some tests.
