Fix complicated union of INTEGER constraints
A constraint that was an union of integer ranges:
Type ::= INTEGER (lb1..ub1 | ... | lbN..ubN)
would sometimes (depending on the values) not all always be properly
combined to a single effective range, but would become:
Type ::= INTEGER (lb2..ub2) (lb3..ub3)
If that type was used in a SEQUENCE:
S ::= SEQUENCE {
v Type
}
the constraint would be simplified, taking the intersection of the
ranges.
