max-tile remains off by default until more testing is performed but I would
like to check in the fixes that are known so far to prevent this patch getting too big

max_tile was provisionally adopted at the working group meeting 2017-Oct-10

This patch fixes the following issues:
- max_tile is fixed to suport superblock size 64x64 as well as 128x128 (ext_partition support)
- max_tile is fixed in combination with loop_restoration
- max_tile is fixed in combination with ext_tile (Bug: 1013)
- max_tile is fixed in combination with lv_map and 64x64 subperblock (lv_map memory allocation
  fixed for 64x64 superblock)
- max_tile reports the size of the first tile for inspection.c used by the analyzer
