Parameters:

value - bitset describing the default nullness (see Binding.NullnessDefaultMASK)

annotation - the NNBD annotation

scopeStart - start of the source range affected by the default

scopeEnd - end of the source range affected by the default

sourceStart -

Returns:

enclosing binding that already has a matching NonNullByDefault annotation, or the special binding NOT_REDUNDANT, indicating that a different enclosing nullness default was found, or null to indicate that no enclosing nullness default was found.
