Prior to this commit, the `"ret_void"` argument needed to be explicitly provided to `CodeGenLLVM::AddFunction` and `CodeGenLLVM::DeclareFunction`. If this was inconsistent with the `builtin::ret()` usage within the `PrimFunc`, this could cause the incorrect return type in the generated LLVM-IR, resulting in LLVM IR verification failures. This commit removes the `"ret_void"` argument, instead using the type annotation in `PrimFunc::ret_type`, removing this opportunity for inconsistency. This PR is intended to fix a ROCm regression reported in apache#14901 (comment).
