In f47db80cc07, 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 until e2e7168a214b, 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. Backports 6d3ef04893bdea3e7aa08be3cce5141902836a31
