* i386.h (LIBGCC2_LONG_DOUBLE_TYPE_SIZE): Set to 128bit for x86_64
	(BOOL_TYPE_SIZE, SHORT_TYPE_SIZE, INT_TYPE_SIZE,
	 FLOAT_TYPE_SIZE, LONG_TYPE_SIZE, MAX_LONG_TYPE_SIZE,
	 DOUBLE_TYPE_SIZE, LONG_LONG_TYPE_SIZE): New constants.
	(BITS_PER_WORD, UNITS_PER_WORD, POINTER_SIZE, PARM_BOUNDARY,
	 STACK_BOUNDARY): Set properly for 64bits.
	(MAX_BITS_PER_WORD, MIN_UNITS_PER_WORD): New constants.
	(EMPTY_FIELD_BOUNDARY): Define using BITS_PER_WORD.
	(BIGGEST_FIELD_ALIGNMENT): Set to 128 for 64bits.
	(MOVE_MAX): Set to 16.
	(MOVE_MAX_PIECES): 8 for 64bit.
