PowerPC: Add future hwcap2 bits
This patch adds support for the two new HWCAP2 fields used by the
__builtin_cpu_supports function. It adds support in the target_clones
attribute for -mcpu=future.
The two new __builtin_cpu_supports tests are:
__builtin_cpu_supports ("isa_3_1")
__builtin_cpu_supports ("mma")
The bits used are the bits that the Linux kernel engineers will be using for
these new features.
