rs6000: Enable new built-in support, with test suite and altivec.h changes

This patch enables the new built-in infastructure for the Power back end.
To avoid any patches causing regressions that would affect bisection, this is a
combined patch that also includes all the test suite changes and the necessary
modifications to altivec.h.  The patches included here are the following:

https://gcc.gnu.org/pipermail/gcc-patches/2021-November/584638.html
https://gcc.gnu.org/pipermail/gcc-patches/2021-September/578613.html
https://gcc.gnu.org/pipermail/gcc-patches/2021-November/584829.html
https://gcc.gnu.org/pipermail/gcc-patches/2021-September/578614.html

The third of these four was broken up into multiple patches for review, but
effectively all pieces of it were accepted after an independent patch that
modified the error handling for overloaded builtins.
