The test gcc.dg/vect/slp-perm-8.c fails on arm-none-eabi with neon enabled:
FAIL: gcc.dg/vect/slp-perm-8.c scan-tree-dump-times vect "vectorized 1
loops" 2

The test expects 2 loops to be vectorized, while gcc successfully vectorizes
3 loops in this test using neon on arm. This patch adjusts the expected
output. Fixed test passes on qemu for arm and powerpc.

OK for trunk?

Thanks,
Greta

        * gcc.dg/vect/slp-perm-8.c (dg-final): Adjust expected number
        of vectorized loops for arm with neon.
