Subject: [PATCH -mm 17/43] powerpc CORE_DUMP_USE_REGSET

This switches powerpc to using the user_regset-based code for ELF core
dumps.  The core dumps come out exactly the same either way, except that
the NT_PPC_VMX note is now omitted for any thread that never touched its
Altivec registers (thread_struct.vr_used).
