[PATCH v3 0/9] decodetree: Add non-overlapping groups

[Richard Henderson]

This is a feature that Peter requested for completing the
neon decodetree conversion.

Changes for v3:
  - Remove check for less than 2 patterns in a group.

Changes for v2:
  - Rebase on master, which includes some generic python cleanups.
  - Indentation error message restored.
  - 4 new testcases

Peter, do you want me to include the final patch in any
decodetree pull request, or shall I leave that for you
to pick up through the target-arm.next tree?
