NO_ARGS_ARRAY is currently only used on 32bit x86 non-MS Windows machines.
It's doubtful that the few instructions saved make any difference on
modern machines...
NO_ARGS_ARRAY assumes that function arguments are passed on the stack,
but that is not true when using the -mregparam option, or when the
compiler decides to change the calling convention (like gcc-4.5 can
when using -flto).
Do we still want to keep NO_ARGS_ARRAY?
