Traditionally objc had two entry points, objc_msgSend for scalar
return methods, and objc_msgSend_stret for struct return convention
methods. But on arm64 the second was not needed (since arm64 doesn't
use an argument register for the struct return pointer) so it was removed.
The code that dispatches to the objc object checker when it sees some
flavor of objc_msgSend was not aware of this change so was sending the
wrong arguments to the checker.

This is the conclusion of an effort to get LLDB's Python code
structured into a bona-fide Python package. This has a number
of benefits, but most notably the ability to more easily share
Python code between different but related pieces of LLDB's Python
infrastructure (for example, `scripts` can now share code with
`test`).
