Wrong encoding for C extension on golang

[MouseSplinter]

Hi, all,
I find that current encoding for C extension on golang is wrong. And the struct inst doesn't adapt 16 bit compressed instruction well.Is there any plan to solve this problem? If not, I want to extend the struct inst with some field named like rvc_funct3、rvc_funct4、rvc_funct2 and rvc_funct6 , which I can encode compressed instruction to. Or, maybe I should reuse the funct7 and funct3 to encode the funct3、funct4、funct2 and funct6 of compressed instruction. Which method would you like to take to meet the golang codegen?
