glsl: Add GLSL 1.40 textureSize() implementations for sampler2DRect.
By setting lod to 0 in the builtin function implementation, we avoid
needing to update all the visitors to ignore LOD in this case, when
the hardware drivers actually want to ask for LOD 0 for rectangular
textures.
Fixes piglit spec/GLSL-1.40/textureSize-*Rect.
v2: Change style of looking for substrings.
