We recently (commit 6a5d9ff261) started
to use std::source_location instead of std::experimental::source_location.
However, this does not work on clang 14, because libc++ 12's
<source_location> only works if __builtin_source_location, and that is
not available on clang 14.
clang 15 is just three months old, and several relatively-recent
distributions still carry clang 14 so it would be nice to support it
as well.
So this patch adds a trivial compatibility header file, which, when
included and compiled with clang 14, it aliases the functional
std::experimental::source_location to std::source_location.
It turns out it's enough to include the new header file from three
headers that included <source_location> - I guess all other uses
of source_location depend on those header files directly or indirectly.
We may later need to include the compatibility header file in additional
places, bug for now we don't.
