/*!\brief AV1 block partition search (partition estimation and partial search).
*
* \ingroup partition_search
* Encode the block by applying pre-calculated partition patterns that are
* represented by coding block sizes stored in the mbmi array. Minor partition
* adjustments are tested and applied if they lead to lower rd costs. The
* partition types are limited to a basic set: none, horz, vert, and split.
*
* \param[in] cpi Top-level encoder structure
* \param[in] td Pointer to thread data
* \param[in] tile_data Pointer to struct holding adaptive
data/contexts/models for the tile during encoding
* \param[in] mib Array representing MB_MODE_INFO pointers for mi
blocks starting from the first pixel of the current
block
* \param[in] tp Pointer to the starting token
* \param[in] mi_row Row coordinate of the block in a step size of MI_SIZE
* \param[in] mi_col Column coordinate of the block in a step size of
MI_SIZE
* \param[in] bsize Current block size
* \param[in] rate Pointer to the final rate for encoding the current
block
* \param[in] dist Pointer to the final distortion of the current block
* \param[in] do_recon Whether the reconstruction function needs to be run,
either for finalizing a superblock or providing
reference for future sub-partitions
* \param[in] pc_tree Pointer to the PC_TREE node holding the picked
partitions and mode info for the current block
*
* \remark Nothing is returned. The pc_tree struct is modified to store the
* picked partition and modes. The rate and dist are also updated with those
* corresponding to the best partition found.

/*!\brief Top level function to pick block mode for non-RD optimized case
*
* \ingroup partition_search
* \callgraph
* \callergraph
* Searches prediction modes, transform, and coefficient coding modes for an
* individual coding block. This function is the top-level function that is
* used for non-RD optimized mode search (controlled by
* \c cpi->sf.rt_sf.use_nonrd_pick_mode). Depending on frame type it calls
* inter/skip/hybrid-intra mode search functions
*
* \param[in] cpi Top-level encoder structure
* \param[in] tile_data Pointer to struct holding adaptive
* data/contexts/models for the tile during
* encoding
* \param[in] x Pointer to structure holding all the data for
* the current macroblock
* \param[in] mi_row Row coordinate of the block in a step size of
* MI_SIZE
* \param[in] mi_col Column coordinate of the block in a step size of
* MI_SIZE
* \param[in] rd_cost Pointer to structure holding rate and distortion
* stats for the current block
* \param[in] bsize Current block size
* \param[in] ctx Pointer to structure holding coding contexts and
* chosen modes for the current block
*
* \remark Nothing is returned. Instead, the chosen modes and contexts necessary
* for reconstruction are stored in ctx, the rate-distortion stats are stored in
* rd_cost. If no valid mode leading to rd_cost <= best_rd, the status will be
* signalled by an INT64_MAX rd_cost->rdcost.
