Can you explain why you want `call-indirect-overlong` in lime1?  Is it because you want to be able to link files compiles with multi-table?  i.e. do you want/expect type relocations at every call_indirect site?   If so then perhaps a better name might be `call-indirect-relocatable`?   Or maybe even `multi-table-compatible`?  Sorry for the bikesheding and this late stage..
