Subject: Moves inter mode count updates to update_stats
X-Git-Tag: v1.4.0~288^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e7570493b8e99756321e44608913cff60eb37d41;p=libvpx

Moves inter mode count updates to update_stats

This makes the inter_mode counts update consistent with other symbols.
Also, forward updates should work corerctly now.
