    Implement scoped type variables in pattern synonyms
    
    This fixes Trac #11351.   The implementation is pretty
    simple, happily.
    
    I took the opportunity to re-order the prov/req context
    in builder-ids, which was confusingly backwards.
    
    (cherry picked from commit e2c7b7ee976dcabf12002265ddbe58017b794cb8)
