i965: Handle nested uniform array indexing
When converting a uniform array reference to a pull constant load, the
`reladdr` expression itself may have its own `reladdr`, arbitrarily
deeply. This arises from expressions like:
a[b[x]] where a, b are uniform arrays (or lowered const arrays),
and x is not a constant.
Just iterate the lowering to pull constants until we stop seeing these
nested. For most shaders, there will be only one pass through this loop.
