trans_vmv_x_s, trans_vmv_s_x, trans_vfmv_f_s and trans_vfmv_s_f aren't setting vstart = 0 after execution. This is usually done by a helper in vector_helper.c but these functions don't use helpers. We'll set vstart after any potential 'over' brconds, and that will also mandate a mark_vs_dirty() too.
