Zachary Turner fa9d44b037 [llvm-pdbutil] Support dumping CodeView from object files.
We have llvm-readobj for dumping CodeView from object files, and
llvm-pdbutil has always been more focused on PDB.  However,
llvm-pdbutil has a lot of useful options for summarizing debug
information in aggregate and presenting high level statistical
views.  Furthermore, it's arguably better as a testing tool since
we don't have to write tests to conform to a state-machine like
structure where you match multiple lines in succession, each
depending on a previous match.  llvm-pdbutil dumps much more
concisely, so it's possible to use single-line matches in many
cases where as with readobj tests you have to use multi-line
matches with an implicit state machine.

Because of this, I'm adding object file support to llvm-pdbutil.
In fact, this mirrors the cvdump tool from Microsoft, which also
supports both object files and pdb files.  In the future we could
perhaps rename this tool llvm-cvutil.

In the meantime, this allows us to deep dive into object files
the same way we already can with PDB files.
