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 Reviewers: asmith, zturner, rnk, labath, clayborg, lldb-commits Reviewed By: zturner Subscribers: aleksandr.urakov, stella.stamenova, JDevlieghere, lldb-commits Differential Revision: https://reviews.llvm.org/D49980 llvm-svn: 339649
