[llvm] [CloneFunction] Remove check that is no longer necessary (PR #92577)

[Danila Malyutin via llvm-commits]

https://github.com/danilaml created https://github.com/llvm/llvm-project/pull/92577

We do not need to concern ourselves with CGSCC since all remaining CG related updates went away in fa6ea7a419f37befbed04368bcb8af4c718facbb as pointed out by @nikic in https://github.com/llvm/llvm-project/pull/87963#issuecomment-2113937182.
