The struct x1f4_1stscope_type operator definition extension is to
include the
X1f4_E4_MXCA_LIST bit in its bits1 bits list field. The
remaining optimization parameters are to be introduced via the
struct x1f4_operator_type first extension, in a struct
x1f4_odbA_type definition. That is, the extension1 field of the
struct x1f4_operator_type operator description must point a struct
x1f4_1stscope_type record, whose odbA_data field must point a
struct x1f4_odbA_type record, in turn describing the optimization
parameters.

The optimization transforms expressions like:
(2 + e) + c + 2 (2 + e) + (c + 2)
into:
4 + e + c 4 + e + c
