I forgot to mention that comparing the three tests of placement of the
Having the pass after sched2 generated the same number of PCREL_OPT relocations
as having the pass immediately after reload.
But having the pass just before sched2 resulted in some more PCREL_OPT
relocations. Mostly the number of instructions was the same, but a few
benchmarks had a few more 4-byte instructions generated. It looks like those
new PCREL_OPT relocations replaced a few places where we loaded the address,
but did not do a PCREL_OPT optimization.
