There's no reason to make this any different from the other builders,
since it just creates a collect instruction, and in the next commit
we'll need to create a collect in the first block for prefetch textures.

In order for the load to never straddle the load can't extend past 8
bytes, not 16. For example a vec2 load with align_mul = 8 and
align_offset = 4 can straddle.
Fixes assertion failures when we stop pushing UBOs in the preamble on
a6xx.

Let's assume we have a vec2 collect instruction with killed sources that
are non-contiguous and the entire rest of the register file is blocked,
which can happen when our register target is very tight. It's impossible
to just insert move instructions to resolve this, but we can make space
by swapping one of the killed sources with the value next to the other,
assuming it's also scalar.
This commit implements that idea, preventing us from falling back to the
terrible shuffle-everything approach in this case.

We need the local size in RA for occupancy calculations. Not
initializing these had the unfortunate consequence of
ir3_get_reg_independent_max_waves() returning 0 for compute shaders with
shared variables, disabling the register limiting logic.

There are roughly two cases when it comes to storage images. In the
easy case, we have full hardware support and we can just emit a typed
read/write message in the shader and we're done. In the more complex
cases, we may need to fall back to a typed read with a different format
or even to a raw (SSBO) read.
The hardware has always had basically full support for typed writes all
the way back to Ivy Bridge but typed reads have been harder to come by.
Starting with Skylake, we finally have enough that we at least have a
format of the right bit size but not necessarily the right format so we
can use a typed read but may still have to do an int->unorm or similar
cast in the shader.
Previously, in ANV, we treated lowered images as the default and write-
only as a special case that we can optimize. This flips everything
around and treats the cases where we don't need to do any lowering as
the default "vanilla" case and treats the lowered case as special.
Importantly, this means that read-write access to surfaces where the
native format handles typed writes now use the same surface state as
write-only access and the only thing that uses the lowered surface state
is access read-write access with a format that doesn't support typed
reads. This has the added benefit that now, if someone does a read
without specifying a format, we can default to the vanilla surface and
it will work as long as it's a format that supports typed reads.

This will allow us to avoid postprocessing binaries when they are
loaded from the shaders cache.
LLVM binaries already contain the shader config as part of the ELF,
so it's duplicated and increase the cache entry by 48 bytes. Though,
I don't think that should matter for LLVM.
