示例14: relaxConstraint

/*
 * relaxConstraint returns the least specific TypeConstraint 'tc' that doesn't
 * prevent the intersection of knownType and relaxType(toRelax, tc) from
 * satisfying origTc. It is used in IRBuilder::constrainValue and
 * IRBuilder::constrainStack to determine how to constrain the typeParam and
 * src values of CheckType/CheckStk instructions, and the src values of
 * AssertType/AssertStk instructions.
 *
 * AssertType example:
 * t24:Obj<C> = AssertType<{Obj<C>|InitNull}> t4:Obj
 *
 * If constrainValue is called with (t24, DataTypeSpecialized), relaxConstraint
 * will be called with (DataTypeSpecialized, Obj<C>|InitNull, Obj). After a few
 * iterations it will determine that constraining Obj with DataTypeCountness
 * will still allow the result type of the AssertType instruction to satisfy
 * DataTypeSpecialized, because relaxType(Obj, DataTypeCountness) == Obj.
