    i965/vec4: make offset() work in terms of a simd width and scalar
components

    So that it has the same semantics as the scalar backend implementation. The
    helper will now take a simd width (which is always 8 in vec4 mode) and step
    as many scalar components as specified by that width, respecting the size
of
    the scalar channels.

    v2 (Curro):
      - Remove the assertion in offset(), byte_offset() has the same checks.
      - Use byte_offset() directly instead of add_byte_offset().
      - Make things more clear by explicitly including the vertical stride
        in the byte offset expression.
