c++: Small incremental tweak to source_location::current() folding
I've already committed the patch, but perhaps we shouldn't do it in cp_fold
where it will be folded even for warnings etc. and the locations might not
be the final yet. This patch moves it to cp_fold_r so that it is done just
once for each function and just once for each static initializer.

* cp-gimplify.c (cp_fold_r): Perform folding of
std::source_location::current() calls here...
(cp_fold): ... rather than here.
