Log:
[CGDebugInfo] Set the size and align for reference types
In r253186, I changed the DIBuilder API to now take size and align
for reference types as well. This was done in preparation for upcoming
changes to the Verifier that will validate that sizes match between
DI types and IR values that are declared as having those types.
This updates clang to actually pass the information through.
