  Log Message:
  -----------
  [libc++] Applied `[[nodiscard]]` to some general utilities (#169322)

`[[nodiscard]]` should be applied to functions where discarding the
return value is most likely a correctness issue.
- https://libcxx.llvm.org/CodingGuidelines.html#apply-nodiscard-where-relevant

The following functions/classes have been annotated in this patch:
- [x] `bind_back`, `bind_front`, `bind`
- [x] `function`, `mem_fn`
- [x] `reference_wrapper`
