Fix buffer underrun (invalid read) triggered during diagnostic rendering. The test would overflow when computing '0 - 1'. I don't have a good testcase for this that does not depend on system headers. It did not trigger with preprocessed output, and I had trouble reducing the example. Fixes <rdar://problem/13324594>. Thanks to Michael Greiner for reporting this issue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177201 91177308-0d34-0410-b5e6-96231b3b80d8
