From: Daniel Henrique Barboza <dbarboza@ventanamicro.com>
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.
Fixes: dedc53cbc9 ("target/riscv: rvv-1.0: integer scalar move instructions")
