The test is for loop vectorization producing non-canonical
multiplications. We can now BB vectorize the whole function
when the target supports .REDUC_PLUS for V2SImode but we don't
have a dejagnu selector for that. Disable BB vectorization
like we disabled epilogue vectorization.
Tested on aarch64-linux, pushed.
