, we handled odd-sized tail clearing for the case of hosts that have vector operations, but did not handle the case of hosts that do not have vector ops. This was ok untile2e7168a21
, which changed the encoding of simd_desc such that the odd sizes are impossible. Add memset as a tcg helper, and use that for all out-of-line byte stores to vectors. This includes, but is not limited to, the tail clearing operation in question.
