While it's not entirely clear why a compiler or linker might put this information into an object or PDB file, one has been spotted in the wild which was causing llvm-pdbdump to crash. This patch adds support for reading-writing these sections. Since I don't know how to get one of the native tools to generate this kind of debug info, the only test here is one in which we feed YAML into the tool to produce a PDB and then spit out YAML from the resulting PDB and make sure that it matches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@304738 91177308-0d34-0410-b5e6-96231b3b80d8
