H. Peter Anvin 13587802fe segalloc: DO NOT reset segment numbers
We are not supposed to reset the segment numbers; this was an
attempted fix for a convergence bug that didn't actually exist. The
backend is required to return the same segment number for the same
segment; if it does not, the front end will not converge, but that is
in fact the correct behavior.
