nir: Propagate *2*16 conversions into vectors

If we have code like:

   ('f2f16', ('vec2', ('f2f32', 'a@16'), '#b@32'))

We would like to eliminate the conversions, but the existing rules can't
see into the the (heterogenous) vector. So instead of trying to
eliminate in one pass, we add opts to propagate the f2f16 into the
vector. Even if nothing further happens, this is often a win since then
the created vector is smaller (half2 instead of float2). Hence the above
gets transformed to

   ('vec2', ('f2f16', ('f2f32', 'a@16')), ('f2f16', '#b@32'))

Then the existing f2f16(f2f32) rule will kick in for the first component
and constant folding will for the second and we'll be left with

   ('vec2', 'a@16', '#b@16')

...eliminating all conversions.

v2: Predicate on !options->vectorize_vec2_16bit. As discussed, this
optimization helps greatly on true vector architectures (like Midgard)
but wreaks havoc on more modern SIMD-within-a-register architectures
(like Bifrost and modern AMD). So let's predicate on that.

v3: Extend for integers as well and add a comment explaining the
transforms.

radeonsi: bump SI_NUM_SHADER_BUFFERS to 32

Some app uses more than 8 SSBOs (https://gitlab.freedesktop.org/mesa/mesa/-/issues/2946),
so increase SI_NUM_SHADER_BUFFERS to 32 (which allows 16 SSBOs).

Since we're now using a 64 bits number to track buffers, we could bump
SI_NUM_SHADER_BUFFERS to 48 but that would conflict with Mesa's
MAX_COMBINED_ATOMIC_BUFFERS limit (= 90).

glsl: define gl_LightSource members in ARB_vertex_program order

GLSL shares functionality with ARB_vertex_program but the GLSL
spec defines the gl_LightSource builtin with a member order that
is different from the packing expected in ARB_vertex_program.
This difference introduces a need for specialist lowering code
when handling builtin structs that is not required for normal
uniform structs due to member location mismatches.

Since gl_LightSource can't be redefined it shouldn't matter if
we add the members in the order listed in the spec, just so long
as we add them all. So here we rearrange the definition of the

loader/dri3: Check for window destruction in dri3_wait_for_event_locked

If the underlying X11 window gets destroyed, the event we're waiting
for may never be delivered, in which case xcb_wait_for_special_event
would hang indefinitely.

Solution:

1. Use xcb_poll_for_special_event to check if an event has arrived yet.
2. If not, Wait up to ~1s for XCB's file descriptor to become readable;
   if it does, go back to step 1.
3. If the file descriptor didn't become readable, make a round-trip to
   the X server to check that the window still exists. Go back to step
   1 if it does, otherwise bail.

Also add an early bail-out when it's known that the window was

iris: Implement pipe->texture_subdata directly

Chris Wilson noted that u_default_texture_subdata's transfer path
sometimes results in wasteful double copies.  This patch is based
on an earlier path he wrote, but updated now that we have staging
blits for busy or compressed textures.

Consider the case of idle, non-CCS-compressed, tiled images:

The transfer-based CPU path has to return a "linear" mapping, so upon
map, it mallocs a temporary buffer.  u_default_texture_subdata then
copies the client memory to this malloc'd buffer, and transfer unmap
performs a tiled_memcpy to copy it back into the texture.  By writing
a direct texture_subdata() implementation, we're able to directly do
a tiled_memcpy from the client memory into the destination texture,
resulting in only one copy.

For linear buffers, there is no advantage to doing things directly, so
we simply fall back to u_default_texture_subdata()'s transfer path to
avoid replicating those cases.

We still may want to use GPU staging buffers for busy destinations
(to avoid stalls) or CCS-compressed images (to compress the data),
at which point we also fall back to the existing path.  We thought
to try and use a tiled temporary, but this didn't appear to help.
