Greetings,
Here is a patch for C++20 p0879 - Constexpr for swap and swap related
functions.
This essentially constexprifies the rest of <algorithm>.
Built and tested with C++20 (and pre-c++20) on x86_64-linux.
Ok?

Implement C++20 p0879 - Constexpr for swap and swap related functions.
* include/bits/algorithmfwd.h (__cpp_lib_constexpr_swap_algorithms):
New macro. (iter_swap, make_heap, next_permutation, partial_sort_copy,
There should be a newline after "New macro." and before the next
parenthesized list of identifiers.
The parenthesized lists should not span multiple lines, so close and
reopen the parens, i.e.

Should this value be 201806L?
The new macro also needs to be added to <version>.
