trans_rvv.c.inc: set vstart = 0 in int scalar move insns

Browse Source 
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.
