Added infrastructure for optimizing new CanvasArray types in WebGL

These new CanvasArray types have different semantics than
CanvasPixelArray; out-of-range values are clamped via C cast
semantics, which is cheaper than the clamping behavior specified by
CanvasPixelArray. Out-of-range indices raise exceptions instead of

KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and
