[code-reflection] RFR: Example use of code reflection in translating Java to SPIR-V [v3]

[Steve Dohrmann]

> Example code showing use of code reflection in translation from Java to SPIR-V intermediate language.  For more information on SPIR-V see [https://www.khronos.org/spir](https://www.khronos.org/spir).
> 
> Translates from a Java CoreOps.FuncOp object to a SpirvOps.FuncOp object and then to an entry point in a SPIR-V binary module.  One test is included that demonstrates use and renders the Java model, SPIR-V model, and disassembled binary representations of an example Java method. 
> 
> A subsequent pull-request will provide additional test code, including the ability to test SPIR-V binaries on GPU hardware. 
> 
> Dependencies:
> 
> This code depends on a Java SPIR-V builder API (https://github.com/beehive-lab/beehive-spirv-toolkit).  The toolkit can be installed locally with:
> 
> git clone https://github.com/beehive-lab/beehive-spirv-toolkit 
> cd beehive-spirv-toolkit
> mvn clean install

Steve Dohrmann has updated the pull request incrementally with two additional commits since the last revision:

 - - apply FieldRef, MethodRef changes
   - remove unused imports
 - update README and module header id
