fix to baseline regressions (seg fault in insertSetMemberInits)

Added a check to make sure a field's type has a valid reference type
before inserting initialization code.  This short-circuits runtime
array types which do not.  They remain uninitialized.  A more involved
fix may be to create a reference type for a runtime array type.
