> The multianewarray helper uses quite specific calling convention: caller-pop, arguments
are passed through stack in left-to-right order (for all platforms). The problem is that this
CC is named "CDECL", which is very confusing. Moreover it is ineffective for non-x86_32 platforms,
loosing advantages of register quantity.
> So at least the name should be changed to avoid confusion, or (better) the helper itself
reworked to use appropriate platform CC.
