This reduces the number of BOs that we need for the BO lists during

Currently uses a fairly simple linear search for finding free space,
that could eventually be improved to a binary tree, which with some

We implement the split opcodes, and tell NIR to lower the original ones.
The lowering to LLVM is a little more complicated, but NIR can optimize
the split ones a little better, and some NIR lowering passes that we
might want to use (particularly for doubles) emit the split ones.
This should fix pack/unpackDouble2x32, which seems like a bug since when
we enabled the Float64 capability. It will also fix pack/unpackInt2x32
when we enable the Int64 capability.

Commit e1af20f18a changed the shader_info
from being embedded into being just a pointer. The idea was that
sharing the shader_info between NIR and GLSL would be easier if it were
a pointer pointing to the same shader_info struct. This, however, has
caused a few problems:
1) There are many things which generate NIR without GLSL. This means
we have to support both NIR shaders which come from GLSL and ones
that don't and need to have an info elsewhere.
2) The solution to (1) raises all sorts of ownership issues which have
to be resolved with ralloc_parent checks.
3) Ever since 00620782c9, we've been
using nir_gather_info to fill out the final shader_info. Thanks to
cloning and the above ownership issues, the nir_shader::info may not
point back to the gl_shader anymore and so we have to do a copy of
the shader_info from NIR back to GLSL anyway.
All of these issues go away if we just embed the shader_info in the
nir_shader. There's a little downside of having to copy it back after
calling nir_gather_info but, as explained above, we have to do that
anyway.

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.
