Note: a future commit will expand the sampler message type to the 6 bits
used on Xe2.
v2 (Francisco Jerez): Rebase on 07b9bfacc7 ("intel/compiler: Move
logical-send lowering to a separate file").
v3: Drop XE2_SAMPLER_MESSAGE_SAMPLE_BIAS_MLOD as it does not actually
exist. This resulted in some bigger changes in brw_disasm.c. Noticed
by Sagar.
v4: Now that XE2_SAMPLER_MESSAGE_SAMPLE_MLODc conflicts with
GFX7_SAMPLER_MESSAGE_SAMPLE_GATHER4_PO_C, the determination of
min_lod_is_first must include devinfo->ver or previous platforms will
break.
