    i965/fs/generator: Don't use the address immediate for MOV_INDIRECT

    The address immediate field is only 9 bits and, since the value is in
    bytes, the highest GRF we can point to with it is g15.  This makes it
    pretty close to useless for MOV_INDIRECT.  There were already piles of
    restrictions preventing us from using it prior to Broadwell, so let's get
    rid of the gen8+ code path entirely.

I've tagged it for stable so it should be in 13.0 and it may even get into a
12.0 stable release.
