It looks inconsistent to return 1 for image types and 0 for

used by values_for_type() which always returns 1 for samplers.

For bindless, this value will be bumped to 2 because the

radv/meta: add common shader vertex generation function

Instead of passing in the same 1.0, -1.0 combinations via
vertex buffers, we can just use vertex id to have the vertex
shader build them. This function introduces the generator
code needed, later patches will use this.

radv/ac: add support for indirect access of descriptor sets.

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.

The difference between gen's was just that some lowering flags never get
