Eric Poole cfee2139a0 TriCore Support (#1568) 
* TriCore Support

python sample

* Update sample_tricore.py

Correct attribution

* Update sample_tricore.py

Fixed byte code to execute properly.

* Update sample_tricore.py

Removed testing artifact

* Added tricore msvc config-file.h

* Added STATIC to tricore config and added helper methods to symbol file generation.

* Update op_helper.c

Use built in crc32

* Fix tricore samples and small code blocks are now handled properly

* Add CPU types

* Generate bindings

* Format code
