The tests have now been run on an A55 instead of an A53 (the RK3588 has
both in-order A55 and out-of-order A76, so it makes testing easier).

Changes:
- draw_edges_mmx: support negative strides
- draw_edges_mmx: removed redundant variable assignment (last_line)
- checkasm: merged commits adding mpegvideoencdsp tests
- checkasm: add new tests to fate
- checkasm: test for negative strides
- neon: remove spaces inside {}
- neon: do two lines per loop in pix_sum (faster on A55, slower on A76,
        but a good compromise)

Ramiro Polla (7):
  avcodec/x86/mpegvideoencdsp: support negative strides in
    draw_edges_mmx()
  checkasm/mpegvideoencdsp: add pix_sum, pix_norm1, and draw_edges
  avcodec/aarch64/mpegvideoencdsp: add neon implementations for pix_sum
    and pix_norm1
  avcodec/aarch64/mpegvideoencdsp: add dotprod implementation for
    pix_norm1
  avcodec/x86/mpegvideoencdsp: fix comment for draw_edges_mmx
  avcodec/x86/mpegvideoencdsp: speed up draw_edges_mmx by using memcpy()
  avcodec/mpegvideoencdsp: speed up draw_edges_8_c by inlining it for
    all used edge widths
