This does not include subscript operators.
Before this is re-enabled operators need to be re-implemented. Right now they are the source of a lot of bugs. They cause frequent crashes and mis compiles. Also, templated operators insert a lot of names into global lookup which causes problems.
They also don't work on Windows.
Restore the explicit C++ standard for these tests as the C++ compiler
invocation on Darwin uses the system compiler rather than the just built
clang, which may be sufficiently different to have different default
standards.
This will be cleaned up with the next change to introduce a new
`%target-clangxx` to control the C++ standard.
Do not override the C++ standard explicitly when running the tests.
This will eventually be useful in allowing tests to run against
different C++ standards.
Add a test to verify that C++ out-of-line operator functions are imported correctly.
Includes fixes for armv7 and arm64.
This is part of addressing SR-12748.
