commit a039ddac6d248f06184f1eece05d1da513917d69

Set DECL_ARTIFICIAL on gfortran internal variables.
It seems we sometimes use DECL_ARTIFICIAL as choosing between
different code paths. In order not to make -fdebug-aux-vars
do different things, set DECL_ARTIFICIAL on the variables to
avoid these different code paths (and the corresponding
regressions).
gcc/fortran/ChangeLog:
* trans.c (create_var_debug_raw): Set DECL_ARTIFICIAL
on variables.
(cherry picked from commit 8d76c007afe4c70f51fd56b0e5b89522de5de61f)
