The section of the PRM mentioned in the code comment above this table
says that this format supports the render target write message. Internal
documentation says that this format also supports alpha blending. As a
side effect, this allows CCS_D buffers to be created for images with
this format.

This adds two columns to the format table as well as two helpers for
determining whether or not a given format is supported for typed reads
and writes.

Nothing uses this yet but it serves as a nice bit of documentation
that's relatively easy to find.

The term "lossless compression" could potentially mean multisample
color compression, single-sample color compression or HiZ because they
are all lossless. The term CCS_E, however, has a very precise meaning;
in ISL and is only used to refer to single-sample color compression.
It's also much shorter which is nice.

This causes hangs on Broadwell if you try to render to it. I have no
idea how we managed to not hit this earlier.

We use *64*_PASSTHRU formats to upload vertex attributes of 64 bits
to avoid conversions. From the BDW PRM, Volume 2d, page 586
(VERTEX_ELEMENT_STATE):
"When SourceElementFormat is set to one of the *64*_PASSTHRU
formats, 64-bit components are stored in the URB without any
conversion. In this case, vertex elements must be written as 128
or 256 bits, with VFCOMP_STORE_0 being used to pad the output
as required. E.g., if R64_PASSTHRU is used to copy a 64-bit Red
component into the URB, Component 1 must be specified as
VFCOMP_STORE_0 (with Components 2,3 set to VFCOMP_NOSTORE)
in order to output a 128-bit vertex element, or Components 1-3 must
be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex
element. Likewise, use of R64G64B64_PASSTHRU requires Component 3
to be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex
element."
v2,v3 (Jason):
- Don't delete unused formats.

With the isl_format_supports* helpers, we can now conveniently
report support for this format on Cherry View.

HiZ buffers can be multisampled and, on Broadwell and earlier, simply using
interleaved multisampling with a compression block size of 8x4 samples
yields the correct HiZ surface size calculations. Unfortunately,
choose_msaa_layout was rejecting multisampled HiZ buffers because of format
checks. Now that we have a simple helper for determining if a format
supports multisampling, that's an easy enough issue to fix.

In ca2a8e56285, we updated the format table to add more formats (most of
which are new on SKL) but accidentally marked some integer formats as
filterable. You can't filter an integer format.

There were a lot of formats where support was added on Haswell or later but
we never updated the format table.

This is just a copy-and-paste from brw_surface_formats.c. For the
supports_vertex_fetch function, we do a bit more work so that it properly
handles Bay Trail.
