d4a3b09c4b glsl: Check earlier for MaxTextureImageUnits and MaxImageUniforms
Currently the linker do all the work then check for the limits, which
means num_textures and num_images in shader_info may have to store more
than the limit.  This breaks down now since shader_info was packed and
doesn't expect to store larger invalid values.

To fix this, pull the check before we set the counts in shader_info.
Add necessary plumbing to make sure we bail once those errors are
found.

One drawback of this approach is that for some cases we might not see
the collected errors from various stages, but bail as soon as a stage
breaks the limits.

d0bbf98c96 nir/builder: Add a nir_extract_bits helper
This new helper is better than nir_bitcast_vector because it's able to
take a (mostly) arbitrary range from the source vector.  The only
requirement is that first_bit has to be aligned to the smaller of the
two bit sizes.  It wouldn't be hard to lift that requirement but it's
reasonable for now.

9e440b8d0b spirv: Sort out the mess that is sampled image
This commit makes two major changes.  First, we add a second case to
OpLoad for sampled images which constructs a vtn_sampled_image and
stashes that rather than stashing a pointer to the combined image
sampler like we do for bare samplers and images.  This should be more in
line with how SPIR-V is intended to work and hopefully doesn't cause any
weird problems.  The second is a rework of vtn_handle_texture to assume
that everything has an image but not everything has a sampler.  We also
add a vtn_fail_if for the case where a texture instructions require a
sampler but none is provided.

9cc4c2c916 spirv: Add a vtn_decorate_pointer helper
This helper makes a duplicate copy of the pointer if any new access
flags are set at this stage.  This way we don't end up propagating
access flags further than they actual SPIR-V decorations.  In several
instances where we create new pointers, we still call the decoration
helper directly because no copy is needed.
