There was a problem hiding this comment.
i wonder if we even need the _CCCL_HAS_IF_CONSTEVAL_IN_CXX20 macro anymore. its only remaining use will be in __cccl/dialect.h.

gcc and nvhpc support
auto(expr)even before c++23 as an extension, nvcc supports this since 13.0.This renames
_LIBCUDACXX_AUTO_CASTto_CCCL_AUTO_CASTand allows more efficient implementation viaauto(expr)even in earlier c++ modes.
