[Soot-list] Fast Lookup of SootMethod/SootMethodRef

[Eric Bodden]

I think the reason for the current behavior is that there are some
algorithms in Soot which really like to keep multiple "equal" method
refs apart, even when they are stored in structures like hash sets.
But if you wrap them into EquivalentValue wrappers then this should
actually work. This wrapper dispatches equals/hashCode to special
"equivTo" methods.
