GCN target doesn't support load lanes, so the testcase is expected to fail, other targets create a permuted load here which we then then reject. However some GCN arch don't seem to support the permuted loads either, so the vectorizer tries a gather/scatter. But the indices aren't supported by some target, so instead the vectorizer scalarizes the loads. I can't really test for which architecture is being used by the compiler, so instead this updates the testcase to use one single architecture so we get a consistent result. gcc/testsuite/ChangeLog: PR target/119286 * gcc.dg/vect/vect-early-break_18.c: Force -march=gfx908 for amdgcn.
