Changeset 42cf5d60 in OpenModelica

Improve handling of package constants

• Try to fetch the binding of a package constant from its parent if it doesn't have a binding and is a record field.
• Add case for cref in Expression.nthRecordElement that returns a new cref instead of a record element expression.
• Disable collection of package constants in functions, since it doesn't work properly anyway.
• Move collection of package constants before collection of functions, so that function in package constants are also collected.
