This is patch #3 of 3 to add -mcpu=future support to the PowerPC.
Compared to the previous version of tis patch, I update a comment to say
_ARCH_FUTURE instead of _ARCH_PWR11 that was a typo.
This patch adds simple tests for -mcpu=future.
I have tested these patches on both big endian and little endian PowerPC
servers, with no regressions. Can I check these patchs into the trunk?
