Before this patch, prof_grad_filter calculate
gh[0], gh[1], gv[0], gv[1] and save them to stack.
derive_bdof_vx_vy load them from stack and calculate
gh[0] + gh[1], gv[0] + gv[1].
apply_bdof_min_block load them from stack and calculate
gh[0] - gh[1], gv[0] - gv[1]
This patch add bdof_grad_filter, which calculate gh[0] + gh[1],
gh[0] - gh[1], gv[0] + gv[1], gv[0] - gv[1], and save them to
stack, so derive_bdof_vx_vy and apply_bdof_min_block can use the
results directly.
prof_grad_filter is kept for reuse by other functions in the future.
