  -----------
  [GlobalMerge][PPC] Don't merge globals in llvm.metadata section (#131801)

The llvm.metadata section is not emitted and has special semantics. We
should not merge globals in it, similarly to how we already skip merging
of `llvm.xyz` globals.

Fixes https://github.com/llvm/llvm-project/issues/131394.

(cherry picked from commit 9356091a98c24718572f99b51553838ed664b67a)
