fschneider@google.com eba7136e7b Make IL instructions a doubly-linked list within basic blocks. 
In order to be able to efficiently iterate backwards over instructions
and removing or replacing instructions in the graph we want them to
be a double-linked list inside basic blocks. The list has the following

1. Block entry instructions do not have a previous instruction.
2. The last instruction in a block may or may not have a next instruction:
   - Branches have a NULL-successor.
   - Normal block exits have a block entry instructions as successor.

This CL also makes the accessor for previous and next instruction in this
list non-virtual. This avoidis the current code duplication there.
