The Swift Simplification pass can do more than the old MandatoryCombine pass: simplification of more instruction types and dead code elimination. The result is a better -Onone performance while still keeping debug info consistent. Currently following code patterns are simplified: * `struct` -> `struct_extract` * `enum` -> `unchecked_enum_data` * `partial_apply` -> `apply` * `br` to a 1:1 related block * `cond_br` with a constant condition * `isConcrete` and `is_same_metadata` builtins More simplifications can be added in the future. rdar://96708429 rdar://104562580
