709426b33a [PDB] Restore AST from PDB symbols
Summary:
This patch adds an implementation of retrieving of declarations and declaration
contexts based on PDB symbols.

PDB has different type symbols for const-qualified types, and this
implementation ensures that only one declaration was created for both const
and non-const types, but creates different compiler types for them.

The implementation also processes the case when there are two symbols
corresponding to a variable. It's possible e.g. for class static variables,
they has one global symbol and one symbol belonging to a class.

PDB has no info about namespaces, so this implementation parses the full symbol
name and tries to figure out if the symbol belongs to namespace or not,
and then creates nested namespaces if necessary.

7d2a74fc54 [PDB] Parse UDT symbols and pointers to members (combined patch)
Summary:
In this patch I've tried to combine the best ideas from D49368 and D49410,
so it implements following:

- Completion of UDTs from a PDB with a filling of a layout info;
- Pointers to members;
- Fixes the bug relating to a virtual base offset reading from `vbtable`.
  The offset was treated as an unsigned, but it can be a negative sometimes.
- Support of MSInheritance attribute
