[Bug tree-optimization/55124] [4.8 Regression] ICE in find_or_generate_expression, at tree-ssa-pre.c:2803

Ok, instead of rewriting this mess during stage3 I'll re-instantiate the
failure path (but consistently) of expression insertion so that in this case
we defer to a further insert iteration to fixup things.  I have to keep the
odd code for ssa-pre-28.c though to not regress here.
