This will be more useful when we change the quant mode to increase subpixel
precision and decrease the viewport range (which might not be possible
if the viewport is not centered in the viewport range).
This means that TTN shaders more closely resemble GTN shaders: they have
inputs and outputs as variable derefs, with the variables having their
.driver_location already set up for you.
This will be useful for v3d to do input variable DCE in NIR, which we
can't do when the TTN shaders never have a pre-nir_lower_io stage.

u_transfer_helper already had code to handle treating packed Z32_S8
as separate Z32_FLOAT and S8_UINT resources, since some drivers can't
handle that interleaved format natively.
Other hardware needs depth and stencil as separate resources for all
formats. For example, V3D3 needs this for 24-bit depth as well.
This patch adds a new flag to lower all depth/stencils formats, and
implements support for Z24_UNORM_S8_UINT. (S8_UINT_Z24_UNORM is left
as an exercise to the reader, preferably someone who has access to a
machine that uses that format.)

svga_destroy_shader_variant() itself flushes and retries the command
if there's a failure. So no need for the callers to do it. Other
callers of the function were already ignoring the return value.
This also fixes a corner-case double-free reported by Coverity
(and reported by Dave Airlie).
Tested with various OpenGL apps.

For some reason the 2d engine can't handle this. Red formats get special
treatment there, so perhaps related.

The current state tracker can generate these sometimes. Fixing this is
more involved, and due to some integer math we can generate
divisions-by-zero.

As with a5xx, hidden behind FD_MESA_DEBUG=lrz due to being paranoid
about z-fighting issues with some games (in particular, this was
observed with 0ad on a5xx.. but I think the proper solution to enable
this by default is to figure out how to do driver specific driconf
options).

reg_saved will have 64 bits, and (1 << reg) where reg > 31 has undefined
behavior. (1ull << reg) would be correct for 64 bits.
This commit shifts the other way in order to merge the conditions.
Add the files otherwise things just won't build.
Haven't actually tested it, but it's a small step in the right
direction.
