riccibruno added a comment. I actually have patches for TemplateSpecializationType, PackExpansionType, DependentTemplateSpecializationType and SubstTemplateTypeParmPackType which move the unsigned to the bit-fields in Type. The same could be done for the others I suppose. This assume that the bit-fields of Type have 64 bits available though.
An other one is in ElaboratedType: the member "TagDecl *OwnedTagDecl" is very commonly null (IIRC only non-null for about 600 of the 66k ElaboratedTypes when parsing all of Boost). Therefore we can simply put it in a trailing object and stash a bit in the bit-fields of Type indicating when this pointer is null.
