Fortran] Support absent optional args with use_device_{ptr,addr}
2019-11-11 Tobias Burnus <tobias@codesourcery.com>

gcc/
* langhooks-def.h (LANG_HOOKS_OMP_CHECK_OPTIONAL_ARGUMENT):
Renamed from LANG_HOOKS_OMP_IS_OPTIONAL_ARGUMENT; update define.
(LANG_HOOKS_DECLS): Rename also here.
* langhooks.h (lang_hooks_for_decls): Rename
omp_is_optional_argument to omp_check_optional_argument; take
additional bool argument.
* omp-general.h (omp_check_optional_argument): Likewise.
* omp-general.h (omp_check_optional_argument): Likewise.
* omp-low.c (lower_omp_target): Update calls; handle absent
Fortran optional arguments with USE_DEVICE_ADDR/USE_DEVICE_PTR.
gcc/fortran/
* trans-expr.c (gfc_conv_expr_present): Check for DECL_ARTIFICIAL
for the VALUE hidden argument avoiding -fallow-underscore issues.
* trans-decl.c (create_function_arglist): Also set
GFC_DECL_OPTIONAL_ARGUMENT for per-value arguments.
* f95-lang.c (LANG_HOOKS_OMP_CHECK_OPTIONAL_ARGUMENT):
Renamed from LANG_HOOKS_OMP_IS_OPTIONAL_ARGUMENT; point
to gfc_omp_check_optional_argument.
* trans.h (gfc_omp_check_optional_argument): Subsitutes
gfc_omp_is_optional_argument declaration.
* trans-openmp.c (gfc_omp_is_optional_argument): Make static.
(gfc_omp_check_optional_argument): New function.
libgomp/
* testsuite/libgomp.fortran/use_device_ptr-optional-1.f90: Extend.
* testsuite/libgomp.fortran/use_device_ptr-optional-2.f90: New.
