This used a delicate hack to try to find indirect inputs and skip them
as candidates for pairing. Let's use a better criterion -- no sources --
and pair based on that.
We could do better, but that would require more complex data flow
analysis than we're interested in doing here.

We implement gl_WorkGroupID and gl_LocalInvocationID, which map to
ld_compute_id with special sources.

This allows liveness analysis within a loop to be more fine grained,
fixing RA failures with partial spilled movs within a loop, as well as
enabling a slight reduction of register pressure more generally:
total registers in shared programs: 350 -> 347 (-0.86%)
registers in affected programs: 12 -> 9 (-25.00%)

Just laying the groundwork. Reads and writes should be supported (both
direct and indirect, either int or float, vec1/2/3/4), but no bounds
checking is done at the moment.

This is a corner case that happens a lot with SSBOs. Basically, if we
only read a few components of a uniform, we need to only spill a few
components or otherwise we try to spill what we spilled and RA hangs.

We don't want to load a 128-bit sysval when 64-bits will do. Fixes RA
failures with SSBO indirect writes.

Sometimes a sysval is used to facilitate an instruction but is not the
instruction itself.

This is of course suboptimal for performance, forcing each
glDispatchCompute call to be submitted separately to the kernel and
finish to completion. However, for the initial bring-up of compute jobs,
this simplifies quite a bit.

For each SSBO index we get from Gallium/NIR, we need two pieces of
information in the shader:
1. The address of the SSBO in GPU memory. Within the shader, we'll be
accessing it with raw memory load/store, so we need the actual address,
not just an index.
2. The size of the SSBO. This is not strictly necessary, but at some
point, we may like to do bounds checking on SSBO accesses.

This u_prim.h helper determines the number of outputs for stream output,
given a particular primitive type and a vertex count. This is useful for
statically calculating sizes of stream output buffers (i.e. when there
is no geometry/tessellation shader in use).
This helper will be used in Panfrost's transform feedback
implementation, as you can probably guess since why else would I be
submitting it....
See also dEQP's getTransformFeedbackOutputCount routine.

By optimizing the shader before inlining, we avoid having to redo this
work for each inlined copy of a function. It should also reduce the
memory consumption a bit.
This cuts the KHR-GL46.arrays_of_arrays_gl.SubroutineFunctionCalls2
runtime by 25% on my Icelake. That test compiles many shaders, which
contain large types (dmat4) and division (expensive operations).
