i965: handle OPCODE_SWZ in the glsl path

glsl compiler will not generate OPCODE_SWZ, and as a first step it would
be translated away to a MOV anyway (why?), but later internally this opcode is
generated (for EXT_texture_swizzling).
(cherry picked from commit 4ef1f8e3b52a06fcf58f78c9c36738531b91dbac)
