The vector-compare-1.c testcase fails on S/390 when compiled with -march=z196

Steps to reproduce:
make check-gcc RUNTESTFLAGS="--target_board='unix/-m31/-march=z196' dg-torture.exp=vector-compare-1.c"

FAIL: c-c++-common/torture/vector-compare-1.c   -O3 -fomit-frame-pointer  execution test

lra-remat places an insn (14287) which reads and clobbers the condition code hard register 33 right after (insn 1330) each other making the second depend on the clobbered cc.
