This can't be a regression, as -fselective-scheduling2 was introduced in 4.4.

different testcase, in C, reduced

Crashes in trunk r155248 and 4.4 r154975 with the following command line:
gcc -O2 -fselective-scheduling2 -fsel-sched-pipelining
-fsel-sched-pipelining-outer-loops pr39453.c
(arch is x86_64, but happens with -m32 as well)
