This patch adds simple tests for -mcpu=future.
I have built GCC with the patches in this patch set applied on both little and
big endian PowerPC systems and there were no regressions. Can I apply this
patch to GCC 15?

* gcc.target/powerpc/future-1.c: New test.
* gcc.target/powerpc/future-2.c: Likewise.
