The ICE is not reproduced on P8LE and P9, but pr79439-1.c and vsx-builtin-7.c
are reproducible. It was caused by r276469 enabling inline-functions for O2 by
default, so small functions are inlined, need update the test case due to
instruction count difference. will send a patch if @seurer confirmed the ICE
not exists.
