[Bug fortran/41200] New: allocate: improve a compiler error message for an invalid Fortran code

["jdelia at intec dot unl dot edu dot ar" <gcc-bugzilla at gcc dot gnu dot org>]

The following sample is an invalid Fortran code although the compiler gives an
ICE error message. 

Perhaps, the compiler error message in this case could be improved, e.g. tell
what we are doing wrong. 

Regards,
Jorge.
