    PR modula2/111955 introduce isnan support to Builtins.def

    This patch introduces isnan, isnanf and isnanl to Builtins.def.
    It requires fallback functions isnan, isnanf, isnanl to be implemented =
in
    libgm2/libm2pim/wrapc.cc and gm2-libs-ch/wrapc.c.
    Access to the GCC builtin isnan tree is provided by adding
    an isnan definition and support functions to gm2-gcc/m2builtins.cc.
