    i965/gen7: Enable support for fast color clears.

    This patch adds code to place mcs_state into INTEL_MCS_STATE_RESOLVED
    for miptrees that are capable of supporting fast color clears.  This
    will have no effect on buffers that don't undergo a fast color clear;
    however, for buffers that do undergo a fast color clear, an MCS
    miptree will be allocated (at the time of the first fast clear), and
    will be used thereafter.
