Copy string_view tests from libstdc++
This patch copies the string_view tests from the gcc repository (commit
02a4441f002c).
${gcc}/libstdc++-v3/testsuite/21_strings/basic_string_view ->
${binutils-gdb}/gdb/unittests/basic_string_view
The local modifications are done in the following patch, so that it's
easier to review them.
