    rs6000: Don't ICE when we disassemble an MMA variable [PR101322]

    When we expand an MMA disassemble built-in with C++ using a pointer that
    is cast to a valid MMA type, the type isn't passed down to the expand
    machinery and we end up using the base type of the pointer which leads =
to
    an ICE.  This patch enforces we always use the correct MMA type regardl=
ess
    of the pointer type being used.
