Second stab at target-dependent lowering of everyone's favorite nodes: [SU]ADDO
...
- LowerXADDO lowers [SU]ADDO into an ADD with an implicit EFLAGS define. The
EFLAGS are fed into a SETCC node which has the conditional COND_O or COND_C,
depending on the type of ADDO requested.
- LowerBRCOND now recognizes if it's coming from a SETCC node with COND_O or
COND_C set.

a property. Previous scheme of seaching in interface's list of methods
