All tests pass on x64_64 with and without "-m32" ;)

I took another look at the the front end code and I think I'll add a is_leaf function that:

If the mode is REF, FLEX or ROW: returns false. This is pretty much the current macro.

And also if the mode is STRUCT or UNION: return false if any mode in the PACK_T chain is not leaf, else true.
Return true otherwise.

WDYT?
