Leonard Chan 003b6033e1 [clang] Ensure correct metadata for relative vtables ...

Prior to this, metadata pertaining to the size or address point offsets
into a relative vtable were twice the value they should be (treating
component widths as pointer width rather than 4 bytes). This prevented
some vtables from being devirtualized with D134320. This ensures the
correct metadata is written so whole program devirtualization can catch
these remaining devirt targets.
