  Changed paths:
    M libcxx/include/__config
    M libcxx/include/type_traits

    A libcxx/test/libcxx/utilities/optional/block.objc.pass.mm

  Log Message:
  -----------
  [libc++] Make sure std::is_scalar returns true for block types

Summary:
The compiler already treats them as scalar types, so the library should
too. Furthermore, this allows blocks to be used in more places, for
example in std::optional, which requires an object type.
