This makes the DeoptimizeAll function O(n) instead of O(n^2) where n in the number of optimized functions.

Before this change, DeoptimizeAll iterated over the optimized function list and called DeoptimizingVisitor for each function. The visitor iterated over the optimized function list again to remove the functions that share the same optimized code.

This change partitions the optimized function list into one or more lists of related functions in one pass over the optimized function list.
