The _TwoOperandLIRForm_ flag (LIR requires src1 and dst to match in binary LIR ops) can be set at runtime but each platform defines a default value that is the only one accepted. Although some platform could theoretically support both, there is no realistic scenario for this.
The flag is removed in favour of a constant. This is defined as enum and its assigned value is defined in the platform-specific def.
