[PATCH] D36963: Use sorting instead of a lot of stable_partitions for `ICF::segregate` function

I made some tests and found that without /DEBUG and with /opt:icf versions with and without this path both produce different .exe once in a while (1 out of 5 approximately). With /opt:noref or /opt:noicf build seems to be reproducible. So the problem is definitely somewhere in the icf code, but it was not  introduced in this patch.
