re PR fortran/33197 (Fortran 2008: math functions)

	PR fortran/33197

gcc/fortran/

	ATANH, ERF, ERFC and GAMMA. Add intrinsics BESSEL_{J,Y}{0,1,N},
	ERFC_SCALED, LOG_GAMMA and HYPOT.
	* intrinsic.h (gfc_check_hypot, gfc_simplify_hypot,
	gfc_resolve_hypot): New prototypes.
	* mathbuiltins.def: Add HYPOT builtin. Make complex versions of
	ACOSH, ASINH and ATANH available.
	* gfortran.h (GFC_ISYM_ERFC_SCALED, GFC_ISYM_HYPOT): New values.
	* lang.opt: Add -std=f2008 option.
	* libgfortran.h: Define GFC_STD_F2008.
	* lang-specs.h: Add .f08 and .F08 file suffixes.
	* iresolve.c (gfc_resolve_hypot): New function.
	* parse.c (parse_contained): Allow empty CONTAINS for Fortran 2008.
	* check.c (gfc_check_hypot): New function.
	* trans-intrinsic.c (gfc_intrinsic_map): Define ERFC_SCALE builtin.
	* options.c (set_default_std_flags): Allow Fortran 2008 by default.
	(form_from_filename): Add .f08 suffix.
	(gfc_handle_option): Handle -std=f2008 option.
	* simplify.c (gfc_simplify_hypot): New function.
	* gfortran.texi: Document Fortran 2008 status and file extensions.
	* intrinsic.texi: Document new BESSEL_{J,Y}{0,1,N} intrinsics,
	as well as HYPOT and ERFC_SCALED. Update documentation of ERF,
	ERFC, GAMMA, LGAMMA, ASINH, ACOSH and ATANH.
	* invoke.texi: Document the new -std=f2008 option.
