I'm not exactly sure when zeroing safelen is required.  We do use
safelen for #pragma GCC ivdep as well I think.  That is, if the
loop does not use GOMP_SIMD_LANE is it still required to zero safelen?

That is, for example I don't see any GOMP_SIMD_LANE stuff in
gcc.dg/vect/vect-simd-clone-5.c but it was failing.

Thus - can you take the 2nd part and propose a patch please?
