Software Vertex Processing allows:

In particular shaders can get more constants.

rendering, but hardware rendering, as llvmpipe and dx10+ hw
have the same limits...)

This is considered a second class path. Even apps asking for
"Mixed Vertex processing" (ie the ability to switch to swvp
on demand) do not use the feature much. Some just initialize
more constants than the normal limit at the start of the
application, but never use more than the normal limit.
When the apps do not need the software vertex processing
features, they do not seem to turn it on. This means it is
ok if that path is slow.

anv/cmd_buffer: Rework descriptor dirtying in set_subpass

We have a DIRTY_RENDER_TARGETS flag and that makes a lot more sense than
just dirtying fragment descriptors.  We're checking for it in some of the
gen7 code but unfortunately, nothing was setting it and it didn't do what
it was supposed to do in cmd_buffer_flush_state.

anv/wsi: Advertise UNORM formats as well as sRGB

Because WSI images are created with VkImageCreateInfo::flags explicitly set
to 0, they don't ever have the VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT set.
This means that you can't create an image view of it with a different
format so applications can't render directly in sRGB (without automatic
encoding) unless we actually advertise UNORM formats.  There are a lot of
applications that want to do their own sRGB conversion, so we should allow
for that.  We do, however, make UNORM come after sRGB in the list so that
the default for dumb apps that just grab the first thing is to render in
linear and let the sRGB conversion happen automatically.
