    PowerPC64: Tidy stub type changes
    
    It made sense before I started using separate fields for main type and
    sub type to add a difference in main type to the type (thus keeping
    sub type unchanged).  Not so much now.
    
            * elf64-ppc.c (ppc_merge_stub): Simplify stub type change.
            (ppc_size_one_stub): Likewise.
