DianQK 533b7c1f6c [GlobalOpt] Don't replace the aliasee if it has other references. ...

As long as aliasee has `@llvm.used` or `@llvm.compiler.used` references, we cannot do the related replace or delete operations. Even if it is a Local Linkage, we cannot infer if there is no other use for it, such as asm or other future added cases.
