[IRLinker] Don't add duplicate named MD node operand to dest module (#146020) 
Fix llvm.ident exploding when linking many bitcode files in libclc. This
should de-duplicate other named metadata as well, e.g.
opencl.spir.version and opencl.ocl.version.

This PR is a re-submit of https://reviews.llvm.org/D20582 (authored by
Matt Arsenault) with update that only checks MD node pointer for
duplication according to review comment in that PR.
