    [POWERPC] Add SPE registers to core dumps
    
    This makes the SPE register data appear in ELF core dumps, using the
    new n_type value NT_PPC_SPE (0x101).  This new note type is not used
    by any consumers of core files yet, but support can be added.  I don't
    even have any hardware with SPE capabilities, so I've never seen such
    a note.  But this demonstrates how simple it is to export register
    information in core dumps when the user_regset style is used for the
    low-level code.
