rs6000, remove the vec_xxsel built-ins, they are duplicates

The following undocumented built-ins are covered by the existing overloaded
vec_sel built-in definitions.

  const vsc __builtin_vsx_xxsel_16qi (vsc, vsc, vsc);
same as vsc __builtin_vec_sel (vsc, vsc, vuc);  (overloaded vec_sel)

  const vuc __builtin_vsx_xxsel_16qi_uns (vuc, vuc, vuc);
same as vuc __builtin_vec_sel (vuc, vuc, vuc);  (overloaded vec_sel)

  const vd __builtin_vsx_xxsel_2df (vd, vd, vd);
same as  vd __builtin_vec_sel (vd, vd, vull);   (overloaded vec_sel)

  const vsll __builtin_vsx_xxsel_2di (vsll, vsll, vsll);
same as vsll __builtin_vec_sel (vsll, vsll, vsll);  (overloaded vec_sel)

  const vull __builtin_vsx_xxsel_2di_uns (vull, vull, vull);
same as vull __builtin_vec_sel (vull, vull, vsll);  (overloaded vec_sel)

  const vf __builtin_vsx_xxsel_4sf (vf, vf, vf);
same as vf __builtin_vec_sel (vf, vf, vsi)          (overloaded vec_sel)

  const vsi __builtin_vsx_xxsel_4si (vsi, vsi, vsi);
same as vsi __builtin_vec_sel (vsi, vsi, vbi);      (overloaded vec_sel)

  const vui __builtin_vsx_xxsel_4si_uns (vui, vui, vui);
same as vui __builtin_vec_sel (vui, vui, vui);      (overloaded vec_sel)

  const vss __builtin_vsx_xxsel_8hi (vss, vss, vss);
same as vss __builtin_vec_sel (vss, vss, vbs);      (overloaded vec_sel)

  const vus __builtin_vsx_xxsel_8hi_uns (vus, vus, vus);
same as vus __builtin_vec_sel (vus, vus, vus);      (overloaded vec_sel)

This patch removed the duplicate built-in definitions so users will only
use the documented vec_sel built-in.  The __builtin_vsx_xxsel_[4si, 8hi,
16qi, 4sf, 2df] tests are also removed.

gcc/ChangeLog:
	* config/rs6000/rs6000-builtins.def (__builtin_vsx_xxsel_16qi,
	__builtin_vsx_xxsel_16qi_uns, __builtin_vsx_xxsel_2df,
	__builtin_vsx_xxsel_2di,	__builtin_vsx_xxsel_2di_uns,
	__builtin_vsx_xxsel_4sf, 	__builtin_vsx_xxsel_4si,
	__builtin_vsx_xxsel_4si_uns, 	__builtin_vsx_xxsel_8hi,
	__builtin_vsx_xxsel_8hi_uns): Remove 	built-in definitions.

gcc/testsuite/ChangeLog:
	* gcc.target/powerpc/vsx-builtin-3.c (__builtin_vsx_xxsel_4si,
	__builtin_vsx_xxsel_8hi, __builtin_vsx_xxsel_16qi,
	__builtin_vsx_xxsel_4sf, __builtin_vsx_xxsel_2df,
	__builtin_vsx_xxsel): Change built-in call to overloaded built-in
	call vec_sel.
