[PATCH 1/13] rs6000, Remove __builtin_vsx_cmple* builtins

[Carl Love <cel@linux.ibm.com>]

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.

gcc/ChangeLog:
	* config/rs6000/rs6000-builtin.cc (RS6000_BIF_CMPLE_16QI,
	RS6000_BIF_CMPLE_U16QI, RS6000_BIF_CMPLE_8HI,
	RS6000_BIF_CMPLE_U8HI, RS6000_BIF_CMPLE_4SI, RS6000_BIF_CMPLE_U4SI,
	RS6000_BIF_CMPLE_2DI, RS6000_BIF_CMPLE_U2DI, RS6000_BIF_CMPLE_1TI,
	RS6000_BIF_CMPLE_U1TI): Remove case statements.
	config/rs6000/rs6000-builtins.def (__builtin_vsx_cmple_16qi,
	__builtin_vsx_cmple_2di, __builtin_vsx_cmple_4si,
	__builtin_vsx_cmple_8hi, __builtin_vsx_cmple_u16qi,
	__builtin_vsx_cmple_u2di, __builtin_vsx_cmple_u4si,
	__builtin_vsx_cmple_u8hi): Remove buit-in definitions.
