[PATCH, libstdc++] Two parts of C++20 p1032...

These patches are modest reworkings of previous patches. The patch for char_traits was pretty much approved already.  But in response to a comment from François I at least added __copy_backwards, and used ptrdiff_t instead of size_t parameters and I put all the mem* wrappers in a __detail names

Implement the part of C++20 p1032 Misc constexpr bits.

Here is another chunk of p1032. Jonthan, I plan to get it all except maybe string::copy. I can't figure out how to test without being able to create a constexpr string object. And anything I do will probably collide with your work on constexpr string. p1032 would be a tiny patch on top of that

Re: C++ PATCHes to run testsuite in C++14 mode

Jason, I noticed while converting some of my test cases to use the new targets that gnu targets don't seem to work. It doesn't matter for the test cases at hand but we might want to consider target gnu++11 target gnu++11_only target gnu++1y target gnu++1y_only
