Description

Avoid undefined behavior and enable asserts in ClampTest. The old code here wasn't being careful to avoid int32_t overflow in slow_check. Fix that. R_ASSERT hasn't been doing anything for a while. As a result, there are a couple bugs in SkClampRange, marked as such and commented out. The asserts also weren't quite passing, so I fixed them up (allowing 0xFFFF to be considered either as part of the ramp or part of V1.)
