Codegen is attempting to use a register that is not available (it is not part of the allocatable register list <https://source.chromium.org/chromium/chromium/src/+/main:v8/src/codegen/x64/register-x64.h;l=31;drc=5ca8523b8c9ff9a7b3e7eb349d8fc7566f660675>). Perhaps it's trying to satisfy an invalid register assignment request from interface-descriptors?
