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
