"Solves" expressions of {@code inst_next2}

<p>
Works like the constant solver, but takes the value of {@code inst_next}, which is given by the
assembly address and the resulting instruction length.

<p>
<b>NOTE:</b> This solver requires backfill, since the value of {@code inst_next2} is not known
until possible prefixes have been considered.
