rs6000, add overloaded vec_sel with int128 arguments

Extend the vec_sel built-in to take three signed/unsigned/bool int128
arguments and return a signed/unsigned/bool int128 result.

Extending the vec_sel built-in makes the existing buit-ins
__builtin_vsx_xxsel_1ti and __builtin_vsx_xxsel_1ti_uns obsolete.  The
patch removes these built-ins.

The patch adds documentation and test cases for the new overloaded
vec_sel built-ins.
