copied over from libstdc++'s testsuite. To preserve the structure
and help with comparison with the original tests, the file names
have been preserved, and only minimal modification was done to have
them compile against gdb::string_view instead of std::string_view:
- std::string_view->gdb::string_view, etc.
- ATTRIBUTE_UNUSED in a few places
- wrap each file in a namespace so they can all be compiled as a
single unit.
- libstdc++'s license and formatting style was preserved.
