    Revert "[FIX] Do not copy an llvm::function_ref if it has to be reused"
    
    This fix doesn't seem to be right (function_ref can/should be passed by
    value) so I'm reverted it to see if the buildbots decide to explain
    what's wrong.
    
    This reverts commit 857bf5da35af8e1f9425e1865dab5f5fce5e38f2.
