Zachary Turner e759e99a67 [llvm-pdbdump] Simplify options and output.
This removes a wealth of options, and instead now only provides
three options.  -symbols, -types, and -compilands.  This greatly
simplifies use of the tool, and makes it easier to understand
what you're going to see when you run the tool.
