and its test. Minidump context structures now interoperate more easily with snapshot CPUContext structures, while maintaining identical layout to before. This is facilitated by reusing the Fxsave types for the substructures which were completely identical, and by using compatible logic to initialize the minidump and snapshot structures for testing.
