Move all the NIR related debug environmental variables in a single
NIR_DEBUG one.
Use NIR_DEBUG=help to print all the available options.
v2:
- Use a macro to simplify (Marcin, Jason)
- Remove wrong changes (Marcin)
v3 (Marcin):
- Remove rendundant NIR mentioning in option descriptions.
- Unwrap option descriptions.
- Ensure the constant is unsigned.
- Use extern array to remove switch.
v4:
- Add missing kernel shader (Jason).
- Add unlikely() (Marcin).

This saves a bunch of generated code to pack up the extra NULLs to get to
4 args, and saves executing the conditions in nir_build_alu() to then skip
those NULLs.

Unused variable vector_elements is now used in return from
function decode_type_from_blob instead of encoded.basic.vector_elements.
In the code we can see how those variables were equated
and then the operations were made exactly to vector_elements.
But variable didn't pass into any other variables or functions.

In some non-trivial cases (the amber script file in the merge
request description) phi instruction has more than 32 elements
in predecessors tree and that isn't recursion, just large tree.
In that case, phis not fully converted into a register or mov,
but successfully removed.
The fix removes the counter and adds container of visited blocks.

spirv_to_nir sometimes wraps derefs in vec2 or mov instructions as part of
its texture handling. These get in the way of
nir_rematerialize_derefs_in_use_blocks_impl. Running copy propagation
should get rid of the extra move instructions and get us back to intact
deref chains for everything except variable pointer use-cases.

constant-propagated during inlining without LTO. Move it to a .c file so
we just have one copy, saving 2.8MB from libnir.a on an amd64 release
build.
