Render target surfaces always start at binding table index 0.
This is required for us to use headerless FB writes, which we
really want to do. So, we'll never change that.
Given that, it's not necessary to look up a wm_prog_data field
which we already know contains 0. We can drop the dependency in
brw_renderbuffer_surfaces (Gen4-5)...which was already confusingly
missing from gen6_renderbuffer_surfaces.

brw_hw_type_to_reg_type() needs to know only whether the file is
BRW_IMMEDIATE_VALUE or not, which is not a valid file for the
destination. gcc and clang will evaluate __builtin_strcmp() at compile
time, so we can use it to pass a constant file for the destination.

Previously the brw_inst{,_set}_{dst,src0,src1}_reg_type() functions
provided access to the hardware encodings for the register types. We
often mixed these with the logical BRW_REGISTER_TYPE_* enums (which
themselves used to be the hardware format!) with bad results.
With that functionality now available with the hw_ versions (see
previous commit), we now add functions that take the logical
BRW_REGISTER_TYPE_* enums and convert into the hardware format and vice
versa. To do the conversion we also have to provide the file.
Note the asymmetry between the two functions: the new getter reads the
file from the instruction word, and to ensure that is always set the
setter writes both the file and the type.

I'm going to encapsulate all of the logic dealing with register types in

Rename the parameters for the hardware encodings from type -> hw_type at
the same time.

The hardware encodings often mean different things depending on whether

These vaguely corresponded to the hardware encodings, but that is purely
historical at this point. Reorder them so we stop making things "almost
work" when mixing enums.
The ordering has been closen so that no enum value is the same as a
compatible hardware encoding.

UB and B type encodings are the same as UV and VF. Noticed when writing
the following patch.
Reviewed-by: Scott D Phillips <scott.d.phillips@intel.com>
The destination stride must be equivalent to a dword if VF is used.
Also, since the only compaction table entires with "i:vf" have the
destination as "r:f" specifically check that the destination is of type
float.

Note that there's no point in testing on G45, since its compaction is
the same as Gen5. Same logic applies to Gen7 variants and low-power

ISL already offers functions to fill out most kinds of SURFACE_STATE,
so why not handle null surfaces too?
Null surfaces are simple, so we can just take the dimensions, rather
than an entirte fill structure.

Vulkan allows you to do a submit whose only job is to wait on and

BLEND_STATE packing was modified to be variable-length in:
9670124e31 genxml: Make BLEND_STATE command support variable length array.
The initial gen10.xml still had the old, fixed-length style
definition for BLEND_STATE. So gen10_upload_blend_state would
overwrite the packed BLEND_STATE_ENTRYs with its own fixed array
of all-zero entries when packing BLEND_STATE. This caused
BLEND_STATE upload to not work at all.
