0f25bb8283 nir: Add helpers for lazy var creation. 
This should make writing some lowering/meta code easier.  It also keeps
the num_inputs/outputs updated, when sometimes passes forgot to do so (for
example, nir_lower_input_attachments updated for one of the two vars it
creates).  The names of the variables change in many cases, but it's
probably nicer to see "VERT_ATTRIB_POS" than "in_0" or whatever.

I've only converted mesa core (compiler and GL), not all the driver meta
code.

ace8a7068e nir: fix 2 bugs in nir_create_passthrough_tcs 
- VAR31 was ignored.
- Only a half of the 16-bit slot was passed through, though I'm not sure
  if nir_lower_io handles vec8. The slots are only for GLES and I don't
  think a passthrough TCS is possible with GLES.

Fixes: a8e84f50bc - nir: Add helper to create passthrough TCS shader

5d3895d13b nir: Add way to create passthrough TCS without VS nir 
In the case of disk-cache hits, radeonsi no longer has the nir shader
around.  So add a way to create a passthrough TCS with just the VS
output locations.

a8e84f50bc nir: Add helper to create passthrough TCS shader 
Based on si_create_passthrough_tcs() as that seemed the most generic of
the various different backend driver implementations.  Uses the
load_tess_level_outer_default and load_tess_level_inner_default
intrinsics to load the gl_TessLevelOuter and gl_TessLevelInner values,
so driver will somehow need to implement those to load the values set
by pipe_context::set_tess_state() or similar.
