Class TransformationConstructComposite has been renamed to TransformationCompositeConstruct, to correspond to the name of the SPIR-V instruction (as is done with e.g. TransformationCopyObject). Running tests revealed an issue related to checking dominance in TransformationReplaceIdWithSynonym, which is also fixed here.
