c++: Fix non-portable default argument of make_auto_1 [PR104197]
Avoid using the macro current_template_depth, which expands to an
expression that uses __FUNCTION__, within the signature of a function.
PR c++/104197
gcc/cp/ChangeLog:
* pt.cc (make_auto_1): Use -1 as a placeholder default argument
for level.
