Eric Anholt 2e833b16bc nir/lower_amul: Use num_ubos/ssbos instead of recomputing it.
Now that num_ubos is correctly maintained, we can just trust it.  Fixes an
assertion failure in freedreno I triggered on
dEQP-GLES31.functional.ubo.random.all_per_block_buffers.1 for reasons I
don't really understand.

Jason Ekstrand 611f654fcf nir/deref: Don't try to compare derefs containing casts
One day, we may want copy_prop_vars or other passes to be able to see
through certain types of casts such as when someone casts a uint64_t to
a uvec2.  However, for now we should just avoid casts all together.

David Stevens d8fdb8dab4 nir: Add colorspace support to YUV lowering pass
This change adds support for BT709 and BT2020 colorspace to the YUV
lowering pass. The default remains BT601.

This change also fixes minor imprecision in the last digits of the BT601
offsets due to computation from rounded values when the math was
simplified.

That's an attempt at replacing the complex __int64_to_float() and
__float_to_int64() implementations found in float64.glsl by a simpler
native NIR equivalent.

Thanks to that, we can have lower those conversion without having to

Jason Ekstrand d70fff99c5 nir: Use a single list for all shader variables
Instead of having separate lists of variables, roughly sorted by mode,
use a single list for all shader-level NIR variables.  This makes a few
list walks a bit longer here and there but list walks aren't a very
common thing in NIR at all.  On the other hand, it makes a lot of things
like validation, printing, etc. way simpler.  Also, there are a number
of cases where we move variables from inputs/outputs to globals and this
makes it way easier because we no longer have to move them between
lists.  We only have to deal with that if moving them from the shader to
a nir_function_impl.

Vulkan drivers are expected to call this with use_clipdist_array set

Neil Roberts 56846a2b68 nir/schedule: Add an option for a fallback scheduling algorithm
The current scheduling algorithm favors parallelism a bit too
aggressively and sometimes generates shaders that fail register
allocation. This happens even if the threshold is set to zero to force
it to always use the CSR instruction choosing algorithm.

This patch adds an option to use an even more aggressive fallback that
just always picks the instruction with the shortest maximum delay in the
hope that that will generate the least register pressure. The intention
is to use this as a last resort after register allocation fails in order
to at least have a working shader.
