When we start doing cp iteratively, we hit the case that we've already
`cmps.s.*` into a `cmps.s.ne p0.x, ...`.. when we try to do that again
we can invert the logic condition. So check specifically the condition
to prevent this.
TODO we could maybe be more clever about this to combine conditions.
But why isn't that happening in nir? For example, see
dEQP-GLES31.functional.ssbo.layout.single_basic_array.packed.bool

There can be multiple (for ex.) f32f16's from a single source, in
particular appearing in different blocks. We need to update all uses
of the src which had conversion folded in, not all the uses of the
individual cov. Also, to avoid invalidating the ssa use info that was
gathered at the beginning of the pass, don't actually eliminate the
cov, but instead change it to a simple mov that the cp pass can gobble
up.

We have to fixup the meta:split half flag, because `ir3_split_dest()` is
called before we fixup the dest type. But we should fixup both the
split src and dest, as well as the thing it is splitting.

If we're inserting a mov to resolve a conflict between meta:collect's
(ie. for .zyx type swizzles, etc), we should use the correct precision.

It does pick up a few more cf/cp opportunities, according to sharder-db.
But don't think it will be measurable.
But this will allow some future simplification to cp by pulling out it's
internal iteration.

For a6xx, since we use same VBO state for binning and VS, we need to
preserve potentially unused inputs. This needs to be done before DCE.
So move it before we add earlier DCE passes.

Or do the easy thing and claim we always changed something. It is kinda
hard and not worth the effort to determine for real.
Also rip out unused error handling. This pass should never fail. And
we weren't even actually checking the return.
And while we're at it, switch over to taking the 'struct ir3 ir*`
instead of ctx, to standardize with the other passes.

Later when we do this pass iteratively, we can drop some of the internal
iteration and just rely on this pass getting run until there is no more
progress.

In a later patch, this will get folded into an IR3_PASS() macro, at
least for most passes. But to do that, it is better to standardize
on printing the ir3 after the pass.

SymbolInfoTy was modified in LLVM 11. It is also in MCDisassembler.h now
and we don't have to duplicate it anymore.

This was wrong, if anything it should be sorted by device_location, and NIR usually
provides this.
