[NO ISSUE][IDX][COMP] Creating an open index on non-declared fields

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
This patch is to fix creating an open index on non-declared fields.
When compiling the CREATE INDEX DDL statement, it is assumed
that all nested record fields will be of type ARecordType. However, for
open indexes, any nested non-declared record field will be optional.
In this case, the type will be AUnion(ARecordType) which results
in type casting exceptions for certain situations. An example is:
CREATE INDEX idx ON ds(a.b.c: int, a.b.d: string). Both a and b could
have the type AUnion(ARecordType). This patch takes care of such cases.
