Predicates with 'let PredicateCodeUsesOperands = 1' want to examine
matched operands. When we encounter predicate code that uses operands,
analyze its named operand arguments and create a map between argument
index and name. Later, when leaf node with name is encountered,
emit GIM_RecordNamedOperand that will store that operand at its
argument index in a operand list. This operand list will be argument
to c++ code of the predicate.
