David pointed out to me that pr48258-2 was failing on AIX, and it was failing
under Linux as well. In terms of the Linux failures, this was because the test
was failing if the xxsldwi was generated. I decided the test conditions were
too specific, and loosened them to just check that the compiler did vectorize
the reductions, but not to count how many instructions were generated.
David does this also fix the AIX side of things and can be checked in?

conditions to verify the reduction code is vectorized.
