i965/fs: Implement GL_CLAMP behavior on texture rectangles on gen6+.

We were doing saturate-based clamping on the [0,width] or [0,height]
coordinate, which meant only the first pixel was addressable.

Fixes piglit ARB_texture_rectangle/texwrap-RECT-bordercolor

NOTE: This is a candidate for the 8.0 release branch.
