Overaligned and underaligned types (i.e. types where the alignment has been increased or decreased using the aligned and packed attributes) weren't being correctly handled in all cases, as the unadjusted alignment should be used.

This patch also adjusts getTypeUnadjustedAlign to correctly handle typedefs of non-aggregate types, which it appears it never had to handle before.
