There was a problem hiding this comment.
No change requested: Missing vvv arrows. This isn't worth resetting testing, I'll clean it up later.

And enable support for
source_locationfor Clang.I've observed that there're already some unprotected uses of
constevalin C++20/23 modes, which should have proved thatconstevalgets well with MSVC and Clang. EDG is not well tested, but it is claimed that immediate functions are supported since 5.1. So I thinkconstevalis also well supported.I think
_CONSTEVALis still useful since there may be some other candidate functions for_CONSTEVALthat are needed for pre-C++20.After this change, there'll be only one occurrence of
_CONSTEVAL, which is in<random>:STL/stl/inc/random

Edit:
__cpp_constevalbut acceptsconstevalwithout error.__builtin_COLUMN().__builtin_COLUMN()seem unchanged between Clang15 and 17 (Godbolt link).
