While working on the patch for PR101460, I noticed that we were losing the
expression location when folding class prvalue expressions. The final patch
doesn't fold class prvalues, but this still seems a worthwhile change. I
don't add location wrappers for scalar prvalues because many callers are
trying to fold them away.
Tested x86_64-pc-linux-gnu, applying to trunk.
gcc/cp/ChangeLog:
* constexpr.c (cxx_eval_outermost_constant_expr): Copy
expr location to result.
