PR analyzer/93779 reports an ICE in gfortran with -fanalyzer
that was fixed for GCC 10 by a workaround in
f76a88ebf089871dcce215aa0cb1956ccc060895; the tree code in
question is a FUNCTION_DECL.

Given that I want to rework the above patch at some point, it seems
prudent to add test coverage to ensure the ICE doesn't come back,
which this patch does.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.

OK for master?
