I don't see how we can say x->count is loop invariant, the GIMPLE memory model
allows aliasing of 'g' via 'x->count' since the effective type of 'g' can
be a struct XX (and the store via 'g' doesn't change

If we change "c3 = a" to "c3 = x->b", GCC can optimize it without IPA. It seems
VRP is working for this case.

They are more similar to e.g. GNU printf %m , something that doesn't take any
