Add the `amdgpu_cs_chain` and `amdgpu_cs_chain_preserve` keywords to
LLVM IR and make sure we can parse and print them. Also make sure we
perform some basic checks in the IR verifier - similar to what we check
for many of the other AMDGPU calling conventions, plus the additional
restriction that we can't have direct calls to functions with these
calling conventions.
