Log:
  Pull in r354515 from upstream libc++ trunk:
  
    Fix the build with gcc when `-Wredundant-decls` is passed
  
    Summary:
  
    gcc warns that `__throw_runtime_error` is declared both in
    `<__locale>` and `<stdexcept>`, if `-Wredundant-decls` is passed on
    the command line; this is the case with FreeBSD when ${WARNS} == 6.
  
    Since `<__locale>` gets its first declaration via a transitive
    include of `<stdexcept>`, and the second declaration is after the
    first invocation of `__throw_runtime_error`, delete that second
    declaration.
