radv: Only use PKT3_OCCLUSION_QUERY when it doesn't hang.

PKT3_OCCLUSION_QUERY hangs when used in a nested IB. This only
calls it when in a primary command buffer and we change
GetQueryPoolResults to not need it. CmdCopyQueryPoolResults
still needs it so we break that behavior for secondary command buffers.
However, that would hang already and using an unitialized value is
better than a hang.

svga: fix MSVC build error after PIPE_CAP_USER_INDEX_BUFFERS removal

Need to specify the zero for the struct initializer.  My earlier test
of the patch series was with MinGW, not MSVC.

Trivial.

vc4: Lazily emit our FS/VS input loads.

This reduces register pressure in both types of shaders, by reordering the
input loads from the var->data.driver_location order to whatever order
they appear first in the NIR shader.  These instructions aren't
reorderable at our QIR scheduling level because the FS takes two in
lockstep to do an interpolation, and the VS takes multiple read
instructions in a row to get a whole vec4-level attribute read.

shader-db impact:
total instructions in shared programs: 76666 -> 76590 (-0.10%)
instructions in affected programs:     42945 -> 42869 (-0.18%)
total max temps in shared programs: 9395 -> 9208 (-1.99%)
max temps in affected programs:     2951 -> 2764 (-6.34%)

Some programs get their max temps hurt, depending on the order that the
load_input intrinsics appear, because we end up being unable to copy
propagate an older VPM read into its only use.

vc4: Refactor the load_input code out of the intrinsic code.

It's going gain most of ntq_setup_inputs(), so simplify it first.

vc4: Track the last block we emitted at the top level.

This will be used for delaying our VPM reads (which must be unconditional)
until just before they're used.

vc4: Emit max number of temps in the shader-db output.

We need to be paying attention to optimization's impact on this -- even if
we reduce instruction count, increasing max temps in general is likely to
cause us to fail to register allocate on some shaders, which means that
those won't run at all.

anv/blorp/clear_subpass: Only set surface clear color for fast clears

Not all clear colors are valid.  In particular, on Broadwell and
earlier, only 0/1 colors are allowed in surface state.  No CTS tests are
affected outright by this because, apparently, the CTS coverage for
different clear colors is pretty terrible.  However, when multisample
compression is enabled, we do hit it with CTS tests and this commit
prevents regressions when enabling MCS on Broadwell and earlier.

glsl: Raise a link error for non-SSO ES programs with a TES but no TCS.

OpenGL allows the TCS to be missing and supplies an implicit passthrough
shader, but OpenGL ES does not (see section 7.3 of the ES 3.2 spec,
cited above in the code).

One open question is how to handle this for ARB_ES3_2_compatibility.
This patch raises the link error for all ES shading language programs,
but it might make sense to base it on the API.  The approach taken in
this patch is more restrictive, but should still allow any valid ES
programs to work in GL.

   "This extension allows the fragment shader to control whether values in
    gl_SampleMaskIn[] reflect the coverage after application of the early
