Desktop OpenGL ignores all precision qualifiers.
Also, the lowering pass doesn't work if precision qualifiers are not set,
which is only possible with desktop OpenGL, causing random behavior.

Some hw can narrow 32b const/uniform to 16b on load.. and in particular
lowering constants to 16b would break const->uniform lowering. Allow
them to lower temps to 16b, while skipping consts.
Initially it is set to the same value as LowerPrecisionTemporaries, to
preserve the current behavior.

Similar to other skips for texture queries that don't actually sample
the texture and which results are not packed.
We can't use nir_tex_instr_is_query() here to skip the lowering for all
queries since that causes regressions in Piglit. Apparently, we do want
to lower some of the query results. In particularly, the LOD query.

Instead of having separate lists of variables, roughly sorted by mode,
use a single list for all shader-level NIR variables. This makes a few
list walks a bit longer here and there but list walks aren't a very
common thing in NIR at all. On the other hand, it makes a lot of things
like validation, printing, etc. way simpler. Also, there are a number
of cases where we move variables from inputs/outputs to globals and this
makes it way easier because we no longer have to move them between
lists. We only have to deal with that if moving them from the shader to
a nir_function_impl.
