intel/fs: Remove min_dispatch_width spilling decision from RA

Move the decision one level up, let brw_compile_*() functions use the
spilling information to decide whether or not a certain width
compilation can spill (passed via run_*() functions).

The min_dispatch_width was used to compare with the dispatch_width and
decide whether "a previous shader is already available, so don't
accept spill".

This is replaced by:

- Not calling run_*() functions if it is know beforehand a smaller width
  already spilled -- since the larger width will spill and fail;

- Explicitly passing whether or not a shader is allowed to spill.  For
  the cases where the smaller width is available and haven't spilled,
  the larger width will be compiled but is only useful if it won't
  spill.

Moving the decision to this level will be useful later for variable
group size, which is a case where we want all the widths to be allowed
to spill.

lima/ppir: use a ready list in node_to_instr

After the recent optimizations in ppir lowering that increase options
for combining, node_to_instr now may have multiple options of nodes to
insert and needs to decide which is better.
For example, if an instruction uses both a varying and a texture, there
are two nodes nodes that can be inserted to the load varying slot in the
same instruction (ld_var and ld_coords). It is much more advantageous to
pipeline the load texture coords since that enables the higher precision
path for texture coordinates. However, with the current recursive
expansion, this cannot be influenced.

This simple ready list implementation in node_to_instr allows it to
choose the next node to expand based on a priority score, rather than
relying on the random order coming from the recursive expansion.

Other than preferring nodes with pipeline output (which covers ld_coords
vs ld_var), nodes using later slots in the pipeline are now expanded
first, allowing node_to_instr to make all of the earlier (pipelineable)
nodes available in the ready list so the best one can be chosen when
picking nodes for the earlier slots.

glsl: stop cascading errors if process_parameters() fails

Generally we do not completely stop compilation as soon as we see an error,
instead we continue on to attemp to find any futher errors.

This means we shouldn't be checking state->error to see if any error has
happened during the compilation process, doing so was causing
process_parameters() to fail on completely valid functions if there was
any error found in the shader previously. This then caused the valid
functions not to be found because the paramlist was considered empty,
resulting in the compiler spewing out misleading error messages.

Here we simply add the IR error value to the param list when we have

messaging.
