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

Summary:
There is a reserved range of type indexes for built-in types (like integers).
This will create a symbol for a built-in type if the caller askes for one by
type index. This is also plumbing for being able to recall symbols by type
index in general, but user-defined types will come in subsequent patches.

Instead of creating symbols directly in the findChildren methods of the native
symbol implementations, they will rely on the NativeSession to act as a factory
for these types. This lets NativeSession cache the NativeRawSymbols in its
new symbol cache and makes that cache the source of unique IDs for the symbols.
Right now, this affects only NativeCompilandSymbols. There's no external
change yet, so I think the existing tests are still sufficient. Coming soon
are patches to extend this to built-in types and enums.

There doesn't seem to be a compelling reason why this method should be const
other than it was possible with the DIA implementation. The native session
is going to act as a symbol factory and cache. This could be acheived with
mutable (and the existing const_cast), but it seems cleaner to accept that
this method affects the state of the session.
This change eliminates an existing const_cast.

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.

This allows the ability to call IPDBSession::getGlobalScope with a NativeSession and
to then query it for some basic fields from the PDB's InfoStream.
Note that the symbols now have non-const references back to the Session so that
NativeRawSymbol can access the PDBFile through the Session.
