i965/skl: Always use a header for SIMD4x2 sampler messages
SKL+ overloads the SIMD4x2 SIMD mode to mean either SIMD8D or SIMD4x2
depending on bit 22 in the message header. If the bit is 0 or there is
no header we get SIMD8D. We always wand SIMD4x2 in vec4 and for fs pull
constants, so use a message header in those cases and set bit 22 there.
Based on an initial patch from Ken.
