PR analyzer/94047 reports an ICE, which turned out to be caused
by the erroneous use of TREE_TYPE on the view region's type
in region_model::get_representative_path_var that I introduced
in r10-7024-ge516294a and
fixed in g:787477a226033e36be3f6d16b71be13dd917e982.

This patch adds a regression test for the ICE.
