    i965: Enable regular fast-clears (CCS_D) on gen9+
    
    The set of formats which supports CCS_E is actually fairly small on
    gen9.  However, everything that supports fast-clears on gen8 also
    supports fast-clears on gen9+.  The one very annoying exception is
    that blending is broken for non-0/1 clear colors with sRGB formats.
    In order to solve that problem, we do a resolve to get rid of the
    clear color.  Another option would be to just not fast-clear with
    non-0/1 clear colors however non-0/1 + blending + sRGB is uncommon
    enough that this shouldn't be a significant performance problem.
    
    This appears to help gl_manhattan31_off by about 2%.

    i965/surface_state: Take an isl_aux_usage in emit_surface_state
    
    This commit replaces the generic "flags" parameter with a more explicit
    aux usage parameter.  This leads to a lot of duplicated code at the
    moment but this will all get cleaned up directly.

    i965/miptree: Take an isl_format in prepare_texture
    
    This will be a bit more convenient momentarily.  It's also more correct
    because it makes prepare_texture take sRGB into account.

    i965/miptree: Allow for accessing a CCS_E image as CCS_D
    
    This requires us to start using the partial clear state.  It makes
    things quite a bit more complicated but it's still a fairly
    straightforward exercise in diagram following.

    reinterpretation will work.  This may cause some MCS partial resolves.

    i965/blorp: Do prepare/finish manually
    
    Our attempts to do it automatically are problematic at best.  In order
    to really be precise, we need to know both the desired aux usage and
    whether or not clear is supported.  The current automatic mechanism
    doesn't cover this.  This commit itself is not a functional change since
    it just reworks everything to be in terms of a silly helper.  Later
    commits will switch things over to more sensible ways of choosing usage.

    We keep the old and possibly broken method of determining aux usage

    may call finish_render a bit more accurately.
