Bitfield types emitted by ctfconvert(1) share the name of the base integer type, so a struct field with type "unsigned int : 15" will have a type named "unsigned int". To avoid ambiguity when looking up types by name, add a suffix to names of bitfield types to distinguish them from the base type. Then, if ctfmerge happens to order bitfield types before the corresponding base type in a CTF file, a name lookup will return the base type, which is always going to be the desired behaviour.
