This (for -O2) regressed with
http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=139854
(for -O -fschedule-insns2 it regressed later, when fwprop got added for -O1).
r139854 added sel-sched support, but I believe it wasn't (and isn't) the
default scheduler on x86_64/i?86, thus clearly the branch merge must have
affected also behavior of the normal scheduler.
