handle a_2 = &a
We handle more complex memory processing like &(x_2 +1), but the very simple
a_2 = &a_1
was slipping thru and we were creating the range based on a_1, not &a_1.
Typically we never saw that since earlier passes were propagating this.
turning off FRE exposed this situatuion.
This patch should correct that... verifying now.
