Add -mcpu=future support.
This patch adds the future option to the -mcpu= and -mtune= switches.
This patch treats the future like a power11 in terms of costs and reassociation
width.
This patch issues a ".machine future" to the assembly file if you use
-mcpu=power11.
This patch defines _ARCH_PWR_FUTURE if the user uses -mcpu=future.
This patch allows GCC to be configured with the --with-cpu=future and
--with-tune=future options.
This patch passes -mfuture to the assembler if the user uses -mcpu=future.
