e98c913509 [llvm-pdbdump] Display padding bytes on record layout
When dumping classes, show where padding occurs, and at the end of the
class print statistics about how many bytes total of padding exist in a
class.

Since PDB doesn't specifically contain information about padding, we have
to mimic this by sort of reversing a small portion of the record layout
algorithm (e.g. looking at offsets and sizes and trying to determine
whether something is part of the same field or a new field).

95d726af97 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.

18fcab5833 General usability improvements to generic PDB library.
1. Added some asserts to make sure concrete symbol types don't
   get constructed with RawSymbols that have an incompatible
   SymTag enum value.
2. Added new forwarding macros that auto-define an Id/Sym method
   pair whenever there is a method that returns a SymIndexId.
   Previously we would just provide one method that returned only
   the SymIndexId and it was up to the caller to use the Session
   object to get a pointer to the symbol.  Now we automatically
   get both the method that returns the Id, as well as a method
   that returns the pointer directly with just one macro.
3. Added some methods for dumping straight to stdout that can
   be used from inside the debugger for diagnostics during a
   debug session.
4. Added a clone() method and a cast<T>() method to PDBSymbol
   that can shorten some usage patterns.

eb6ab04fb2 [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.
