Fixes dEQP-VK.pipeline.executable_properties.* on GFX6-7 when
clrxdisasm isn't found. Other generations are also affected if RADV
is built without LLVM.

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.

ACO relies on LLVM to disassemble AMD shaders for ISAs newer than GFX7,
so disassembly needs to be skipped when LLVM is not enabled.
For vkGetPipelineExecutableInternalRepresentationsKHR and vkGetShaderInfoAMD,
the disassembly will not be reported anymore if it can't be generated.

This commit adds the skeleton of a new ACO post-RA optimizer,
which is intended to be a simple pass called after RA, and
is meant to do code changes which can only be done
after RA.
It is currently empty, the actual optimizations will be added
in their own commits. It only has a DCE pass, which deletes
some dead code generated by the spiller.

Latency is estimanted duration of a single wave, ignoring others in the
CU. It is similar to the old cycles statistic except it it's more accurate
and considers memory operations.
The InvThroughput statistic is a combination of MaxWaves, Latency and the
portion of the wave's execution which does not use various resources.

We used that to catch assembly errors in the past,
but now, there are too many hardware features we
use in ACO that are not supported by the LLVM disassembler,
that it is not really suited anymore as a debugging tool.

Streams are really stateful and (IMO) difficult to read for non-trivial
usage. This is also more consistent with NIR and the rest of ACO.
