<pre>Static analysis discovered a memory leak in the handling of ConstraintHolders.
1. ConstraintHolder::create returns a reference to a “new” object.
2. m_variants holds a set of ConstraintHolder objects.
3. m_variants.append(ConstraintHolder::create(…)) copies the returned reference, leaking the new object.
I discussed this with Anders Carlsson, who confirmed that we should just return the object by value here, and return-value-optimization will make sure we efficiently use the memory.</pre>
