gfc_simplify_atand, gfc_simplify_cosd, gfc_simplify_cotand,
gfc_simplify_sind, gfc_simplify_tand, gfc_resolve_trigd2): Add new
prototypes.

resolve_atrigd): Remove prototypes of deleted functions.
* iresolve.c (is_trig_resolved, copy_replace_function_shallow,
gfc_resolve_cotan, get_radians, get_degrees, resolve_trig_call,
gfc_resolve_atrigd, gfc_resolve_atan2d): Delete functions.
(gfc_resolve_trigd, gfc_resolve_trigd2): Resolve to library functions.

gfc_simplify_atand, gfc_simplify_atan2d, gfc_simplify_cosd,
gfc_simplify_sind, gfc_simplify_tand, gfc_simplify_cotand): New
functions.
(gfc_simplify_atan2): Fix error message.
(simplify_trig_call, gfc_simplify_trigd, gfc_simplify_atrigd,
radians_f): Delete functions.
* trans-intrinsic.c: Add LIB_FUNCTION decls for sind, cosd, tand.
(rad2deg, gfc_conv_intrinsic_atrigd, gfc_conv_intrinsic_cotan,
gfc_conv_intrinsic_cotand, gfc_conv_intrinsic_atan2d): New functions.
(gfc_conv_intrinsic_function): Handle ACOSD, ASIND, ATAND, COTAN,
COTAND, ATAN2D.
