    rs6000: Fix .machine cpu selection w/ altivec [PR97367]

    There are various non-IBM CPUs with altivec, so we cannot use that
    flag to determine which .machine cpu to use, so ignore it.
    Emit an additional ".machine altivec" if Altivec is enabled so
    that the assembler doesn't require an explicit -maltivec option
    to assemble any Altivec instructions for those targets where
    the ".machine cpu" is insufficient to enable Altivec.  For example,
    -mcpu=3DG5 emits a ".machine power4".
