[SPARK-22716][SQL] Replace addReferenceObj to reduce the number of global
variables
## What changes were proposed in this pull request?
We have two methods to reference an object `addReferenceMinorObj` and
`addReferenceObj `. The latter creates a new global variable, which means new
entries in the constant pool.
The PR substitutes `addReferenceObj` with `addReferenceMinorObj` where
considered safe.
## How was this patch tested?
added UTs.
