Description
The ctf_add_member always tries to use the underlying size of a type. However, the byte size of a type as returned from ctf_type_size() is not necessarily correct. Whenever we're working with integers we need to explicitly use the bit size encoded in the integer's encoding to determine how large this member is. We still respect the same offset rules as we previously did.
