The call to copyAttributesFrom will copy the visibility, which might assert if it were to produce something invalid like "internal hidden". We avoid it by first creating the replacement with the original linkage and then setting it to internal affter the call to copyAttributesFrom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219184 91177308-0d34-0410-b5e6-96231b3b80d8
