genmodes.c (struct mode_data): Add need_bytesize_adj field.

	* genmodes.c (struct mode_data): Add need_bytesize_adj field.
	(blank_mode): Initialize it.
	(emit_mode_size_inline, emit_mode_nunits_inline,
	emit_mode_inner_inline): New functions.
	(emit_insn_modes_h): Call them and surround their output with
	#if GCC_VERSION >= 4001 ... #endif.
	* machmode.h (GET_MODE_SIZE, GET_MODE_NUNITS, GET_MODE_INNER):
	For GCC_VERSION >= 4001 use mode_*_inline routines instead of
	mode_* arrays if the argument is __builtin_constant_p.
	* lower-subreg.c (dump_choices): Make sure GET_MODE_SIZE argument
	is enum machine_mode.
fortran/
	* trans-types.c (gfc_init_kinds): Make sure GET_MODE_BITSIZE
	argument is enum machine_mode.
