Conflicting debug info for function arguments causes hard-to-debug assertions in the DWARF backend, so the Verifier should reject it. For performance reasons this only checks function arguments from non-inlined debug intrinsics for now. rdar://problem/30520286 This reapplies r295749 after fixing PR32042. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@296543 91177308-0d34-0410-b5e6-96231b3b80d8
