nir: remove old assert
...
This was originally intended to make sure the remap location
was not -1. However the code has changed alot since then,
the location is now never set to -1 and we also handle
components meaning this old assert has been doing comparisions
with the pointer to the array of component data.

Let's use the new gl_state_index16 type everywhere and remove
the typecasts.
This helps reduce the size of gl_program_parameter.

This reduces SGPRs spilling in MadMax, and it also reduces
number of SGPRs in DOW3 and F12017. The number of waves slightly
decreases in F1 but I don't see any performance changes after
benchmarking it. Talos and Serious Sam are not affected because
they don't use any push constants.

If both comparisons are used as sources for instructions other than the
iand, this transformation is detrimental. If the non-identical value in
both compares is constant, the fmin or fmax will be constant-folded
away, so the transformation is always a win.
It is interesting to me that on Iron Lake only 81 shaders have
instruction counts changed, but 726 shaders have cycle counts changed.

nir: Be more conservative about rearranging or-compounded compares
...
If both comparisons are used as sources for instructions other than the
ior, this transformation is detrimental. If the non-identical value in
both compares is constant, the fmin or fmax will be constant-folded
away, so the transformation is always a win.

meson: Use dependencies for nir
...
This creates two new internal dependencies, idep_nir_headers and
idep_nir. The former encapsulates the generation of nir_opcodes.h and
nir_builder_opcodes.h and adding src/compiler/nir as an include path.
This ensures that any target that needs nir headers will have the
includes and that the generated headers will be generated before the
target is build. The second, idep_nir, includes the first and
additionally links to libnir.
This is intended to make it easier to avoid race conditions in the build
when using nir, since the number of consumers for libnir and it's
headers are quite high.
