[llvm-branch-commits] [lld] [NFC][ELF] Create fresh alias in handleNonPreemptibleIfunc (PR #210614)

[Jessica Clarke via llvm-branch-commits]

https://github.com/jrtc27 created https://github.com/llvm/llvm-project/pull/210614

We don't need to copy the full symbol here, we just want an internal
alias to use for the IPLT and IGOTPLT entries and IRELATIVE relocation's
addend.
