    Define __SIZEOF_FLOAT128__ and __SIZEOF_IBM128__.

    Define the sizes of the PowerPC specific types __float128 and __ibm128 if
those
    types are enabled.

    This patch will define __SIZEOF_IBM128__ and __SIZEOF_FLOAT128__ if their
    respective types are created in the compiler.  Currently, this means both
of
    these will be defined if float128 support is enabled.  But at some point in
    the future, __ibm128 could be enabled without enabling float128 support and
    __SIZEOF_IBM128__ would be defined.
