Performs an optimization pass for specialized instructions.

<p/>The following instruction sequences can be optimized:

<pre>
unify_var Xi, get_struc a/0, Xi -> unify_const a/0
get_struc a/0, Xi -> get_const a/0
put_struc a/0, Xi, set_var Xi -> set_const a/0
put_struc a/0, Xi -> put_const a/0
</pre>

@param  instructions The instructions to optimize.

@return An list of optimized instructions.
