Zachary Turner c883a8c6dc [llvm-pdbdump] More advanced class definition dumping.
Previously the dumping of class definitions was very primitive,
and it made it hard to do more than the most trivial of output
formats when dumping.  As such, we would only dump one line for
each field, and then dump non-layout items like nested types
and enums.

With this patch, we do a complete analysis of the object
hierarchy including aggregate types, bases, virtual bases,
vftable analysis, etc.  The only immediately visible effects
of this are that a) we can now dump a line for the vfptr where
before we would treat that as padding, and b) we now don't
treat virtual bases that come at the end of a class as padding
since we have a more detailed analysis of the class's storage
usage.

In subsequent patches, we should be able to use this analysis
to display a complete graphical view of a class's layout including
recursing arbitrarily deep into an object's base class / aggregate
member hierarchy.

Adrian McCarthy 08eb343cce Improves pretty printing of variable types in llvm-pdbdump
* Adds support for pointers to arrays, which was missing
* Adds some tests
* Improves consistency of const and volatile qualifiers
* Eliminates non-composable special case code for arrays and function by using
  a more general recursive approach
* Has a hack for getting the calling convention into the right spot for
  pointer-to-functions

Given the rapid changes happenning in llvm-pdbdump, this may be difficult to
merge.

Zachary Turner a9054ddd9c [CodeView/PDB] Rename a bunch of files.
We were starting to get some name clashes between llvm-pdbdump
and the common CodeView framework, so I took this opportunity
to rename a bunch of files to more accurately describe their
usage.  This also helps in llvm-pdbdump to distinguish
between different files and whether they are used for pretty
dump mode or raw dump mode.
