rs6000, Remove __builtin_vsx_cmple* builtins

The built-ins __builtin_vsx_cmple_u16qi, __builtin_vsx_cmple_u2di,
__builtin_vsx_cmple_u4si and __builtin_vsx_cmple_u8hi should take
unsigned arguments and return an unsigned result.  The current definitions
take signed arguments and return signed results which is incorrect.

The signed and unsigned versions of __builtin_vsx_cmple* are not
documented in extend.texi.  Also there are no test cases for the
built-ins.

Users can use the existing vec_cmple as PVIPR defines instead of
__builtin_vsx_cmple_u16qi, __builtin_vsx_cmple_u2di,
__builtin_vsx_cmple_u4si and __builtin_vsx_cmple_u8hi,
__builtin_vsx_cmple_16qi, __builtin_vsx_cmple_2di,
__builtin_vsx_cmple_4si and __builtin_vsx_cmple_8hi,
__builtin_altivec_cmple_1ti, __builtin_altivec_cmple_u1ti.

Hence these built-ins are redundant and are removed by this patch.
