display the instruction enum being generated in text format.

Clause #2: ex_arith_clause
...
instruction: ADD_BIN16S_BIN16S_BIN16S(0), instrArrayIndex_: 0
Clause #1: ex_comp_clause
OperatorTypeEnum = ITM_GREATER(2024), NumOperands = 3
...
instruction: GT_BIN32S_BIN16S(40), instrArrayIndex_: 218
In addition, some cleanup has been done in expression code.

> Project: Apache Trafodion
> Issue Type: Improvement
> Reporter: Anoop Sharma
> Assignee: Anoop Sharma
> Priority: Minor
>
> Currently, showplan doesnt show the instruction being generated
> for the conversion, comparison, arith, etc expression.
> This instruction is used at runtime to switch to the appropriate
> case stmt which needs to be executed.
> This enhancement is to display the actual case index that is being
> generated.
