  Incorporated patch from haixia@ changing the default implementation of
  array index clamping to use the clamp intrinsic. This works more
  reliably on pure OpenGL ES devices and on Windows.
  
  Added a mechanism in ShBuiltInResources to choose the strategy for
  array index clamping.
  
  BUG=none
  TEST=various out-of-bounds array indexing tests and various WebGL content
