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.
