While comparing the dumps, I noticed -fdump-unnumbered-links no longer
worked like it did back when I introduced it, with the very purpose of
making it easier to compare dumps with and without debug insns.
When the insn_uid was moved out of the u[] array, the indices that
print-rtl tested to tell whether to omit the ids of the prev and next
insns got off by one.
This patch updates the test to match the current indices.
Bootstrapping on ia64-linux-gnu. Ok to install?
