Verify the format is valid and the type is one of the expected
i32 vectors. Verify the used vector types at least cover the
requirements of the corresponding format operand.
These are incremental changes over #89217 , with core logic being the
same. This patch along with #89217 and #91190 should get us ready to enable 64
bit optimizations in atomic optimizer.
Add a new intrinsic, similar to llvm.amdgcn.set.inactive, but used only
in functions with the `amdgpu_cs_chain` or `amdgpu_cs_chain_preserve`
calling conventions. It allows setting the inactive lanes to those of a
value received as a VGPR argument (whereas llvm.amdgcn.set.inactive
usually takes a constant as the value of the inactive lanes).

We only check a subset of the constraints in the verifier:
* that we only call the intrinsic from functions with a restricted set of
calling conventions
* that the 'flags' argument is an immediate
Other checks are (probably) more appropriate for codegen.

This is a follow-up to b71edfaa4ec3c998aadb35255ce2f60bba2940b0
since I forgot the lit.local.cfg files in that one.
Reformatting is done with `black`.
If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.
If you run into any problems, post to discourse about it and
we will try to help.

This indicates an intrinsic parameter is required to be a constant,
and should not be replaced with a non-constant value.
Add the attribute to all AMDGPU and generic intrinsics that comments
indicate it should apply to. I scanned other target intrinsics, but I
don't see any obvious comments indicating which arguments are intended
to be only immediates.
This breaks one questionable testcase for the autoupgrade. I'm unclear
on whether the autoupgrade is supposed to really handle declarations
which were never valid. The verifier fails because the attributes now
refer to a parameter past the end of the argument list.
