This requires that address spaces get propagated to individual values.

constant float[] a : register(b0)
a[3] = 7;

We need to realize that the type of a[3] is "constant float"

This analysis is required for things like

device atomic_uint[] x : register(u0);
InterlockedAdd(&x[0], 1, null);

Here, we have to realize that the type of &x[0] is type "device uint*"
