libstdc++: Fix forwarding of custom IndexType in mdspan [PR121061]
The second bug report in PR121061 is that the conversion of custom
OtherIndexType to IndexType is incorrectly not done via r-value
references.
This commit fixes the forwarding issue, adds a custom IndexType called
RValueInt, which only allows conversion to int via r-value reference.
PR libstdc++/121061
libstdc++-v3/ChangeLog:
* include/std/mdspan (extents::extents): Perform conversion to
index_type of an r-value reference.
(layout_left::mapping::operator()): Ditto.
(layout_right::mapping::operator()): Ditto.
(layout_stride::mapping::operator()): Ditto.
* testsuite/23_containers/mdspan/extents/custom_integer.cc: Add
tests for RValueInt and MutatingInt.
* testsuite/23_containers/mdspan/int_like.h (RValueInt): Add.
* testsuite/23_containers/mdspan/layouts/mapping.cc: Test with
RValueInt.
* testsuite/23_containers/mdspan/mdspan.cc: Ditto.
