    rs6000: Fix PTImode attribute handling [PR106895]

    PTImode is used to generate even/odd register pairs for 128-bit values.
    When PTImode is specified via a type attribute, compilation fails
    because no internal type exists to represent this mode.

    Introduce signed and unsigned PTImode internal builtin types to handle
    PTImode. These __pti_internal types are not documented, as they are not
    intended for direct user use.
