    Fix tsan error in VP9 sub8x8 intra mode search

    This commit fixes issue 1141. The issue was triggered in multi-tile
    encoding. The change properly saves and restores the block context
    information in the real-time mode selection process. It removes
    several redundant memcpy operations in sub8x8 intra block mode
    search.
