Use vector pair load/store for memcpy with -mcpu=future
In the development for the power10 processor, GCC did not enable using the load
vector pair and store vector pair instructions when optimizing things like
memory copy. This patch enables using those instructions if -mcpu=future is
used.

* config/rs6000/rs6000-cpus.def (ISA_FUTURE_MASKS_SERVER): Enable using
load vector pair and store vector pair instructions for memory copy
operations.
(POWERPC_MASKS): Make the bit for enabling using load vector pair and
store vector pair operations set and reset when the PowerPC processor is
changed.
