[CodeExtractor] Don't create bitcasts when inserting lifetime markers (NFCI)

Lifetime marker intrinsics support any pointer type, so CodeExtractor
does not need to bitcast to `i8*` in order to use these markers.

[mlir] Remove more OpBuilder args which are now injected

NFC. Some small changes to make things more consistent but primarily
avoiding old behavior without any further change.

Commit 984744a1314ce165378e7945bc45995302a8cb80 by rjmccall
Fix a variety of minor issues with ObjC method mangling:

- Fix a memory leak accidentally introduced yesterday by using CodeGen's
  existing mangling context instead of creating a new context afresh.

- Move GNU-runtime ObjC method mangling into the AST mangler; this will
  eventually be necessary to support direct methods there, but is also
  just the right architecture.

- Make the Apple-runtime method mangling work properly when given an
  interface declaration, fixing a bug (which had solidified into a test)
  where mangling a category method from the interface could cause it to
  be mangled as if the category name was a class name.  (Category names
  are namespaced within their class and have no global meaning.)

- Fix a code cross-reference in dsymutil.

[DebugInfo] Add types from constructor homing to the retained types list.

Add class types to the retained types list to make sure they
don't get dropped if the constructor is optimized out later.
