6ffa597bcf intel/compiler: Keep track of compiled/spilled in brw_simd_selection_state
We still update the cs_prog_data, but don't rely on it for this state anymore.
This will allow use the SIMD selector with shaders that don't use cs_prog_data.

a0580dadfd intel/compiler: Create a struct to hold SIMD selection state
This is a preparation to decouple the storage of what SIMDs
compiled/spilled from the cs_prog_data.  This will allow reuse
of SIMD selection code by Bindless Shaders.

And since we have a struct now, move the error array there so
reduce the boilerplate of the users.

f13d486ee7 intel/compiler: Initialize SIMDSelectionTest member error.
Fix defect reported by Coverity Scan.

Uninitialized pointer field (UNINIT_CTOR)
uninit_member: Non-static class member error is not initialized
in this constructor nor in any functions that it calls.

3072e6e0da intel/compiler: Don't use SIMD larger than needed for workgroup
Unless we are combining multiple workgroups in the same HW thread,
there's no advantage of using SIMD16 when SIMD8 already fits the
entire workgroup.

4e7b71e00c intel/compiler: Use SIMD selection helpers for variable workgroup size
Variable workgroup size works by compiling as much SIMD variants as
possible and then selecting the right one during dispatch (when the
actual workgroup size is passed to us).

Instead of replicating the logic in a separate function, reuse the
same logic for regular SIMD selection.  And move function for that
together with the remaining simd selection functions.

7558340ebb intel/compiler: Add helpers to select SIMD for compute shaders
Clean up the logic and move it to functions that work with prog_data
attributes to select the right SIMD.  This shouldn't change any
behavior compared to the original.

Having it extracted will allow reuse by Task/Mesh and make it easier
to write tests.
