Leonard Mosescu 4bdbea3ce2 Fix a few small issues in llvm-pdbutil
Running "llvm-pdbutil dump -all" on linux (using the native PDB reader),
over a few PDBs pulled from the Microsoft public symbol store uncovered 
a few small issues:

- stripped PDBs might not have the strings stream (/names)
- stripped PDBs might not have the "module info" stream

Alexandre Ganea d9e96741c4 [Debuginfo][COFF] Minimal serialization support for precompiled types records
This change adds support for the LF_PRECOMP and LF_ENDPRECOMP records required
to read/write Microsoft precompiled types .objs.
See https://en.wikipedia.org/wiki/Precompiled_header#Microsoft_Visual_C_and_C++

This also adds handling for the .debug$P section, which is actually a .debug$T
section in disguise, found only in precompiled .objs.

Zachary Turner 15b2bdfd8b [llvm-pdbutil] Add the ability to explain binary files.
Using this, you can use llvm-pdbutil to export the contents of a
stream to a binary file, then run explain on the binary file so
that it treats the offset as an offset into the stream instead
of an offset into a file.  This makes it easy to compare the
contents of the same stream from two different files.

Zachary Turner abb17cc084 [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.
