We can at least get rid of the if-not-NULL check in a bunch of places.

If I'm going to refactor a bit to use these meta instructions to also
handle input/output, then might as well cleanup the names first.
Nouveau also uses collect/split for names of these meta instructions,
and I like those names better.

Add a placeholder instruction to track texture fetches made prior to FS
shader dispatch. These, like meta:input instructions are scheduled
before any real instructions, so that RA realizes their result values
are live before the first real instruction. And to give legalize a way
to track usage of fetched sample requiring (sy) sync flags.
There is some related special handling for varying texcoord inputs used
for pre-fs-fetch, so that they are not DCE'd and remain in linkage
between FS and previous stage. Note that we could almost avoid this
special handling by giving meta:tex_prefetch real src arguments, except
that in the FS stage, inputs are actual bary.f/ldlv instructions.

It seems like some instructions (noticed this w/ cat3), cannot read HIGH
regs.. cat1 (mov/cov) can, and possibly some/all of cat2.
The blob seems to stick w/ an extra mov into low regs. So lets do the
same.
This fixes WGID on a6xx, which unsurprisingly is related to a lot of
deqp compute fails.

Move (most of) the ir3 compiler to src/freedreno/ir3 so that it can be
re-used by some future vulkan driver. The parts that are gallium
specific have been refactored out and remain in the gallium driver.
Getting the move done now so that it can happen before further
refactoring to support a6xx specific instructions.
NOTE also removes ir3_cmdline compiler tool from autotools build since
that was easier than fixing it and I normally use meson build. Waiting
patiently for the day that we can remove *everything* from the autotools
build.
