Adds FuzzerPassAddCompositeInserts, which randomly adds new OpCompositeInsert instructions. Each OpCompositeInsert instruction yields a copy of an original composite with one subcomponent replaced with an existing or newly added object. Synonym facts are added for the unchanged components in the original and added composite, and for the replaced subcomponent and the object, if possible. Fixes #2859
