[llvm] [llvm][asmprinter] Make call graph section deterministic (PR #167400)

[Paul Kirth via llvm-commits]

https://github.com/ilovepi created https://github.com/llvm/llvm-project/pull/167400

The call-graph-section-assembly.ll tests in CodeGen/X86 and
CodeGen/Aarch64 bot fail under LLVM_REVERSE_ITERATION. These sets should
use SetVector to avoid non-determinism in the ouput.
