    modula-2: Remove uses of scalb*() and significand*() [PR107631]

    The scalb*() functions are obsolete in Posix from 2004 and removed in
    2008.

    The significand*() functions are glibc-only and considered there to be
    obsolescent (not supported for types such as _Float128).

    We can remove them from Modula-2 since they are not required for ISO
    support, but we need to provide an implementation of significand* for
    the "fraction()" functions.
