[foreign] RFR: add test for mutually referring structs

[Henry Jen]

+1.

My eyes and brain hurts looking at it :P

Test hard coded with layout string works on 64-bit platform, that’s not a big deal as it’s what we supported now. However, if we want to use jextract over C declaration code, it can be done with JtregJextract helper class.

Cheers,
Henry
