	* config/rs6000/rs6000-c: Add support for built-in functions
	vector signed char vec_xl_be (signed long long, signed char *);
	vector unsigned char vec_xl_be (signed long long, unsigned char *);
	vector signed int vec_xl_be (signed long long, signed int *);
	vector unsigned int vec_xl_be (signed long long, unsigned int *);
	vector signed long long vec_xl_be (signed long long, signed long long *);
	vector unsigned long long vec_xl_be (signed long long, unsigned long long *);
	vector signed short vec_xl_be (signed long long, signed short *);
	vector unsigned short vec_xl_be (signed long long, unsigned short *);
	vector double vec_xl_be (signed long long, double *);
	vector float vec_xl_be (signed long long, float *);
	* config/rs6000/altivec.h (vec_xl_be): Add #define.
	* config/rs6000/rs6000-builtin.def (XL_BE_V16QI, XL_BE_V8HI, XL_BE_V4SI,
	XL_BE_V2DI, XL_BE_V4SF, XL_BE_V2DF, XL_BE): Add definitions for the builtins.
	* config/rs6000/rs6000.c (altivec_expand_xl_be_builtin): Add function.
	(altivec_expand_builtin): Add switch statement to call altivec_expand_xl_be
	for each builtin.
	(altivec_init_builtins): Add def_builtin for _builtin_vsx_le_be_v8hi,
	__builtin_vsx_le_be_v4si, __builtin_vsx_le_be_v2di, __builtin_vsx_le_be_v4sf,
	__builtin_vsx_le_be_v2df, __builtin_vsx_le_be_v16qi.
	* doc/extend.texi: Update the built-in documentation file for the
