* [DOCS] Fix Sphinx Warnings: the target found for cross-reference warnings

* Fix the warning: undefined label

* Initial TEDD for publishing.

* 1. Fix lint issues. 2. Print intrin.body instead of intrin.name in Schedule Tree.  3. Add examples to top level APIs' comments.  4. Top level APIs don't print Dot string by default, unless outputdotstring is True.

* Fix more lint issues.

* Update top level API argument names and use raw strings to avoid Python lint warnings in the tests.

* Disable TEDD verification, but keep TE construction.

* Stop importing tedd to avoid failure.

* Separate data extraction and visualization. 1. Add API tedd.dump_json(schedule) to dump a json string for the schedule data for visualization.  2. Update tests.  3. Add a tutorial.  4. Add range information to IterVars.

* Update TEDD about InferBound failure.  1. TEDD doesn't call inferbound for DFG. 2. Update tutorial about the InferBound failure.

* 1. Import IPython only if SVG is requested.  This is required to fix a tutorial publishing faliure.  2. Fix test about IPython availability check.

various minor editorial updates - style, grammar, typos.

* add additional switch to handle nested call node

* Fix VM compiler for while loop with free var

- Do not emit __shared__ etc. as part of type for casting

- Fix fp16 reduction kernels with compiler errors:

  "no operator "+" matches these operands, volatile half + volatile half

  This patch inserts casts to remove volatile type qualifier following
  volatile loads (fp16 only). CUDA fp16 library headers should add
  volatile member functions.

- Update have_fp16 to include compute 6.1 GPUs, which do support fp16,
  although their fp16 throughput is low. Updated tests.
