PR121061 shows that the test coverage for custom integer types is
insufficient. Custom IndexTypes are passed to mdspan related objects in
one of two ways:
* as a template parameter pack,
* or as an array/span.
These two cases have different requirements on the (constness of) custom
IndexTypes. Therefore, the tests are restructured as follows:
* allow testing with different custom integers,
* separate code that tests the two cases described above,
* use int_like.h for all tests with custom integers.
The affected tests are for:
* creating extents, layout_stride::mapping and mdspan from
custom integers,
* mapping::operator() and mdspan::operator[].
PR libstdc++/121061
libstdc++-v3/ChangeLog:
* testsuite/23_containers/mdspan/extents/custom_integer.cc:
Enable checking with different custom integers. Improve
checking non-existence of overloads for incompatible custom
integers.
* testsuite/23_containers/mdspan/layouts/mapping.cc: ditto. Also
improve reuse of int_like.h.
* testsuite/23_containers/mdspan/layouts/stride.cc: ditto.
* testsuite/23_containers/mdspan/mdspan.cc: ditto.
* testsuite/23_containers/mdspan/extents/int_like.h: Rename (old
name).
* testsuite/23_containers/mdspan/int_like.h: Rename (new name).
(ThrowingInt): Add.
(NotIntLike): Add.
