// A base class for ensemble matching strategies, which identify Elements in a
// "new" and "old" archives, and match each "new" Element to an "old" Element.
// Matched pairs can then be passed to Disassembler for architecture-specific
// patching. Notes:
// - A matched Element pair must have the same ExecutableType.
// - Special case: Exact matches are ignored, since they can be patched directly
//   without architecture-specific patching.
// - Multiple "new" Elements may match a common "old" Element.
// - A "new" Element may have no match. This can happen when no viable match
//   exists, or when an exact match is skipped.
