6; Note: this test mimics how the naming could have been after parsing in IR in
7; a LLVMContext where some types were already available; but before the
8; remangleIntrinsicFunctions has happened:
9; The @llvm.ssa.copy intrinsics will have to be remangled.
10; In certain cases (as shown here) the remangling can result in a name clash.
11; This is also related to the llvm/test/tools/llvm-linker/remangle.ll testcase that checks
12; a similar situation in the bitcode reader.
