Table – Operand Arrays

There was a macro used for generating two arguments to the Expression Info constructor, which took an argument identifying the array less its suffix.  This macro was removed (the last such macro) and the predefined operand data type arrays were replaced with standard initializer lists.  With an initializer list, the size of the list is available.

The operand count and operand data type array pointer arguments of the Expression Info constructor were replaced with a standard initializer list of data types (with a default of a blank list).  The operand count member is initialized to the size of the operands list.  A standard initializer list is implemented as an array internally.  The begin access function is used to access the beginning of the initializer list to initialize the operand data type array.  The arguments of the expression info instances were modified to the initializer lists.

Another set of related changes were also made.  A null expression info instance was added (with no return value or operands).  The table entries that previously had their expression info pointer member initialized to a null pointer were changed to point to this null expression info instance.  This allowed the removal of the check for a null expression info pointer member in several of the access functions and from the add function.
