This fixes an error when compiling `<experimental/filesystem>` with gcc 4.8.5:

  .../libcxx/src/experimental/filesystem/filesystem_common.h:137:34:
  error: redeclaration ‘T
  std::experimental::filesystem::v1::detail::{anonymous}::error_value() [with T =
  bool]’ d
  iffers in ‘constexpr’
   constexpr bool error_value<bool>() {
                                    ^
  .../libcxx/src/experimental/filesystem/filesystem_common.h:133:3:
  error: from previous declaration ‘T
  std::experimental::filesystem::v1::detail::{anonymous}::error_value() [with T
   = bool]’
   T error_value();
     ^
