Do not walk equivalence set in path_oracle::killing_def.
When killing a def in the path ranger, there is no need to walk the set
of existing equivalences clearing bits. An equivalence match requires
that both ssa-names have to be in each others set. As killing_def
creates a new empty set contianing only the current def, it already
ensures false equivaelnces won't happen.

equivalence set clearing bits.
