Kill second order relations in the path solver.
My upcoming work replacing the VRP threaders with a fully resolving
backward threader has tripped over various corner cases in the path
sensitive relation oracle. This patch kills second order relations when
we kill a relation.
Tested on x86-64 and ppc64le Linux.
