GCC maintainers:

Version 2: Fixed the wording in the changelog per the feedback. With 
this change the patch was approved by Kewen.

The patch removed the built-in __builtin_vsx_xvcvuxwdp as it is covered 
by the overloaded vec_doubleo built-in.

The patch has been tested on Power 10 LE and BE with no regressions.

Please let me know if it is acceptable for mainline.  Thanks.

rs6000, Remove redundant built-in __builtin_vsx_xvcvuxwdp

The built-in __builtin_vsx_xvcvuxwdp can be covered with PVIPR
function vec_doubleo on LE and vec_doublee on BE.  There are no test
cases or documentation for __builtin_vsx_xvcvuxwdp.  This patch
removes the redundant built-in.

gcc/ChangeLog:
     * config/rs6000/rs6000-builtins.def (__builtin_vsx_xvcvuxwdp):
     Remove built-in definition.
