This extends the native reader to enable llvm-pdbutil to list the enums in a
PDB and it includes a simple test. It does not yet list the values in the
enumerations, which requires an actual implementation of
NativeEnumSymbol::FindChildren.
To exercise this code, use a command like:
llvm-pdbutil pretty -native -enums foo.pdb
