URL: https://github.com/llvm/llvm-project/commit/33e21610f9cd40e991b7cac107ba190678970f81 DIFF: https://github.com/llvm/llvm-project/commit/33e21610f9cd40e991b7cac107ba190678970f81.diff LOG: [clang] makes `__is_trivially_equality_comparable` available as a struct Since this was originally a name in library, it needs an escape hatch for versions of Clang that are slightly out-of-sync with libc++.
