Subject: MergeFunctions Pass, removed unused methods from old implementation.

Patch removed next old FunctionComparator methods:
    * enumerate
    * isEquivalentOperation
    * isEquivalentGEP
    * isEquivalentType

This patch belongs to patch series that improves MergeFunctions
performance time from O(N*N) to O(N*log(N)).
