The test case gcc.dg/vect/costmodel/ppc/costmodel-slp-34.c fails if a
loop isn't vectorized. When compiled for little endian, the cost of
vectorizing the loop is deemed too high to vectorize due to unaligned
vector accesses within the loop. Therefore we should skip this test for
LE.
Verified on powerpc64le-unknown-linux-gnu. Is this ok for trunk?
Thanks,
