This adds support for Symbols, StringTable, and FrameData subsection types. Even though these subsections rarely if ever appear in a PDB file (they are usually in object files), there's no theoretical reason why they *couldn't* appear in a PDB. The real issue though is that in order to add support for dumping and writing them (which will be useful for object files), we need a way to test them. And since there is no support for reading and writing them to / from object files yet, making PDB support them is the best way to both add support for the underlying format and add support for tests at the same time. Later, when we go to add support for reading / writing them from object files, we'll need only minimal changes in the underlying read/write code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@305037 91177308-0d34-0410-b5e6-96231b3b80d8
