When I've added template tests for the previous patch, I have noticed that
the current __builtin_source_location behavior is not really __FUNCTION__,
just close, because e.g. in function template __FUNCTION__ is still
"bar" but __builtin_source_location gave "bar<0>".
Anyway, this patch implements above request to follow __PRETTY_FUNCTION__
(on top of the earlier posted patch).
