================
Comment at: llvm/lib/Transforms/Utils/SimplifyCFG.cpp:1621-1633
         unsigned KnownIDs[] = {LLVMContext::MD_tbaa,
-                               LLVMContext::MD_range,
                                LLVMContext::MD_fpmath,
                                LLVMContext::MD_invariant_load,
                                LLVMContext::MD_nonnull,
                                LLVMContext::MD_invariant_group,
                                LLVMContext::MD_align,
                                LLVMContext::MD_dereferenceable,
----------------
Whether these can be replaced with combineMetadataCSE?
