We want to expose more descriptor sets to the applications,
but currently we have a 1:1 mapping between shader descriptor
sets and 2 user sgprs, limiting us to 4 per stage. This commit
check if we don't have enough user sgprs for the number of
bound sets for this shader, we can ask for them to be indirected.
Two sgprs are then used to point to a buffer or 64-bit pointers
to the number of allocated descriptor sets. All shaders point
to the same buffer.
We can use some user sgprs to inline one or two descriptor sets
in future, but until we have a workload that needs this I don't
think we should spend too much time on it.

This adds an initial implementation to allocate the user
sgprs and make sure we don't run out if we try to bind
a bunch of descriptor sets.
This can be enhanced further in the future if we add
support for inlining push constants.

There is some radv specific info we need to gather from shaders
before we get into converting nir->llvm, so we can make
better decisions especially around user sgpr allocation.
This is just an initial placeholder to gather if sample positions
are required in the frag shader.

The current code was broken, and I decided to redesign it instead.
This puts the sample positions for all samples into the queue
constant descriptor buffer after all the spill/ring descriptors.
It then uses a single offset register to point how far into the
samples the samples for num_samples are. This saves one user sgpr
and means we only generate the sample position data in the rare
single case where we need it currently.
This doesn't fix the failing CTS tests without the followup
fix.

This adds support for the tessellation inputs/outputs to the
shader compiler, this is one of the main pieces of the patch.
It is very similiar to the radeonsi code (post merge we should
consider if there are better sharing opportunities). The main
differences from radeonsi, is that we can have "compact" varyings
for clip/cull/tess factors, and we have to add special handling
for these.
This consists of treating the const index from the deref different
depending on the compactness.

This fix is extracted from amdgpu-pro shader traces.
It appears the gather4 workaround for integer types doesn't
work for cubes, so instead if forces a float scaled sample,
then converts to integer.
It modifies the descriptor before calling the gather.
This also produces some ugly asm code for reasons specified
in the patch, llvm could probably do better than dumping
sgprs to vgprs.

The NIR story on conversion opcodes is a mess. We've had way too many
of them, naming is inconsistent, and which ones have explicit sizes was
sort-of random. This commit re-organizes things and makes them all
consistent:
- All non-bool conversion opcodes now have the explicit size in the
destination and are named <src_type>2<dst_type><size>.
- Integer <-> integer conversion opcodes now only come in i2i and u2u
forms (i2u and u2i have been removed) since the only difference
between the different integer conversions is whether or not they
sign-extend when up-converting.
- Boolean conversion opcodes all have the explicit size on the bool and
are named <src_type>2<dst_type>.
Making things consistent also allows nir_type_conversion_op to be moved
to nir_opcodes.c and auto-generated using mako. This will make adding
int8, int16, and float16 versions much easier when the time comes.
