- fix passing aggregate-by-val on x64/sysv: subaggr classification for
aggr *arrays* was wrong (was problematic when there ware exactly 2 8bytes to
be classified, potentially be passed via registers)

call_suite_aggrs for dyncall written in C and Lua. Tests aggregates (structs, unions and arrays) passed by value, along with other, non-aggregate args. Note, arrays are only passed/returned by value as members of structs and unions, as they would decay to a pointer in C if passed to a function, and cannot be returned. So this test suite does not generate any arrays outside of structs and unions. A macro AGGR_MISALIGN can be used in globals.c to intentionally misalign aggregate instances.
