suite_aggrs (still ahead of checked in version of dyncall, sorry): - renaming struct -> aggr - added knobs to: * control struct packing * whether to test immutability of aggr-by-val params * how to copy aggrs (field by field or via = op (which might do a memcpy and thus copy padding garbage, also)) - some macros to reduce file sizes of generated cases - setting default misalignment to 1
