* Make "none" DataType explicit

The None data type is created when converting an empty string to DataType.
Add functions to create it and recognize it. Convert it to the "void" LLVM
type in LLVM codegen.

* Rename "none" to "void"

* Cleanup and sync micro tvm prototype.

* Use /std:c++14 with MSVC.

 * Per tqchen: project has already moved to C++14
 * Presubmit failed for code that built locally on gcc.

* fix ASF lint, and fix add_asf_header too

* [VTA] Fix Pynq driver build issue.
Issue:
When doing vta compile in xilinx FPGA, the pynqdriver.cc report can
not find <vta/driver.h>

Solution:
add related path.

* Fix libvta load fail issue.

issue:
run vta on pynq board libvta.so load failed.

solution:
fixed VTA.make logic issue

Allows Optional<NDArray> and module to be passed with the right type code.

* [CODEGEN][CUDA] Fix a bug when vectorized load&store was involved for "char2"

* Add unittest for char2

* vector element load support char2&add some unittest for vector element load

* Merge common up logic&Support char3&Add unittest for char3

This patch ensures that the output shape from TVM's
Detection_PostProcess is the same as TFLite's and
expands the unit test to confirm this.

* [RELAY] Move frontend utils

The util file currently under frontend is used from
outside of frontend (in qnn/op/legalizations). This suggests
that the file should be pushed up to a higher level.

The benefit from this change is that importing qnn no longer
also imports all the frontends.

- remove unnecessary white spaces from storage kind
- do not start a new scope for vectorization as temporary
  variables are alll uniquely generated.

The above two changes make vectorized code much cleaner.

* Add TopK to ONNX Frontend

* respond to review comments

* [RELAY][PYTORCH]cosh,sinh,log2,log10,log1p op support

* Review comment fixed

* Gradient testcase added

The _type_child_slots can be used to enable quick type checking optimization
by checking the whether the type index is within the bound.

This PR enables these static slots:

- Introduce a static assert to avoid the scenario when a developer forget to
  _type_child_slots when the field is set for the type's parent.
- Revamp and assign static type index to common runtime objects
- Add a DumpTypeTable call to allow developer monitor the current situation
  of type table and offers suggestions for the slots(ideally the slots equals
  the number of children so there is no overflow.

Added missing "tir" in tvm.tir.analysis.verify_gpu_code(f, kwargs)
