Subject: Adapt and integrate string_view tests

The previous patch copied the string_view tests from libstdc++.  This
patch adjusts them in a similar way that the libstdc++ optional tests
are integrated in our unit test suite.

Not all tests are used, some of them require language features not
present in c++11.  For example, we can't use a string_view constructor
where the length is not explicit in a constexpr, because
std::char_traits::length is not a constexpr itself (it is in c++17
though).  Nevertheless, a good number of tests are integrated, which
covers pretty well the string_view features.

gdb/ChangeLog:

	* Makefile.in (SUBDIR_UNITTESTS_SRCS): Add
	string_view-selftests.c.
