r242520 was reverted in r244313 as the expected behaviour of the alias attribute in C is that the alias has the same size as the aliasee. However we can re-introduce adding the size on the alias when the aliasee does not, from a source code or object perspective, exist as a discrete entity. This happens when the aliasee is not a symbol, or when that symbol is private.
