There seems to be another instance of non-determinism which causes the
number of iterations to be either 1 or 3 for one benchmark, depending
on the system. This needs to be investigated and resolved. In the
meantime we do not verify the number of iterations for this benchmark.
When the Attributor run on the IPConstantProp test case for multiple
callbacks it triggered a faulty assertion in the AbstractCallSite
implementation. The callee can well be at argument position 0.
As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

This modification of the currently unused inter-procedural constant
propagation pass (IPConstantPropagation) shows how abstract call sites
enable optimization of callback calls alongside direct and indirect
calls. Through minimal changes, mostly dealing with the partial mapping
of callbacks, inter-procedural constant propagation was enabled for
callbacks, e.g., OpenMP runtime calls or pthreads_create.
