Between 20160805 and 20160811, several libjava tests started to FAIL (mostly
timeouts) on 32-bit Solaris/x86 (both in i386-pc-solaris2.* and
amd64-pc-solaris2.*

A reghunt identified the following patch as the culprit:
2016-08-07 Jan Hubicka <hubi...@ucw.cz>
* tree-ssa-threadbackward.c: Include tree-inline.h
(profitable_jump_thread_path): Use estimate_num_insns to estimate
size of copied block; for cold paths reduce duplication.
(find_jump_threads_backwards): Remove redundant tests.
(pass_thread_jumps::gate): Enable for -Os.
I've not yet determinded what exactly is going wrong.
