    libstdc++: Remove test dependencies on _GLIBCXX_USE_C99_STDINT_TR1
    
    These #ifdef checks should have been removed in r9-2029-g612c9c702e2c9e
    when the u16string_view and u32string_view aliases were changed to be
    defined unconditionally.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/21_strings/basic_string_view/typedefs.cc: Remove
            dependency on _GLIBCXX_USE_C99_STDINT_TR1.
            * testsuite/experimental/string_view/typedefs.cc: Likewise.
    
    (cherry picked from commit fe0e3df6f3751a0164c8e92a0d6519f2e10527a8)
