[Bug fortran/29565] [4.1/4.2/4.3 Regression] ICE in gimplify_var_or_parm_decl, at gimplify.c

This fixes it but has not been regtested.  I was hoping  to have found a
slightly cleaner way to fix this but did not alight on anything that would not
be a big performance.  It's OK for rank 1 arrays but for rank 2 or higher,
carries baggage in the form of various other declarations from the loopinfo
that was never used.
