llvm-pdbdump uses it too.  But yea, having a cross-platform one is good for
obvious reasons, and having a "reference" implementation (e.g. DIA) in
addition to the non-DIA based implementation is desirable because it gives
us an easy way to verify correctness -- by comparing the output of the DIA
based tool and the non DIA based tool.
