    sql: use common registers instead of temp. for constraints data
    
    Prior to this patch, data needed to form tuple to be inserted to
    _fk_constraint and _ck_constraint system spaces (to create corresponding
    constraints) was stored in the range of temporary register. After
    insertion, temporary registers are released. On the other hand, this
    data is required for providing clean-up in case of creation fail (i.e.
    removing already created constraints within one CREATE TABLE statement).
    Hence, instead of using temporary registers let's use ordinary ones.
    
    Closes #4183
