e63d6ed85e spirv: Make vtn_fail and friends trap in debug mode
The SPIR-V parser catches its failures and failed assertions, clean up
and return a failure to the caller.  This is a good default behavior, but
when debugging sometimes is useful to hook the debugger right in the
failed assertion.

7d1bcf1f55 spirv, nir: Handle EmitMeshTasksEXT opcode.
A task shader must use this instruction to specify the dimensions
of the launched mesh shader workgroups.
It is a terminating instruction.

When the task shader doesn't have the optional payload, use the
pre-existing launch_mesh_workgroups intrinsics.

When the task shader has a payload, use a new
launch_mesh_workgroups_with_payload_deref intrinsics which has
a deref that refers to the payload variable.

We also add this new intrinsic to nir_lower_io which lowers this
to the pre-existing explicit intrinsic.

b6543470fe spirv/nir: Set uses_sample_shading from spirv_to_nir

 1) The Vulkan spec says that if a sample-qualified input, SampleID, or
    SamplePosition are in the entry-point's interface, you get
    per-sample dispatch.  This means we really should gather this
    information before dead-code has a chance to delete anything.

 2) We want to be able to add nir_intrinsic_load_sample_pos intrinsics
    as part of lowering passes without causing per-sample interpolation.
    This means nir_gather_info needs to stop gathering it.

260559050a spirv_to_nir: Cast RelaxedPrecision ALU op dests to mediump.
This is controlled by spirv_to_nir_options.relaxed_precision_alu, because
some drivers don't want it.

This gets us mostly 16-bit math on turnip in vk-5-normal.

87d7431198 spirv: Use nir_vec_scalars() to simplify matrix transpose.
This should emit fewer instructions that need to be copy-propagated away.

352e32e5ba nir/builder: Add a nir_trim_vector helper
This pattern pops up a bunch and the semantics of nir_channels() aren't
very convenient much of the time.  Let's add a nir_trim_vector() which
matches nir_pad_vector().
