Pavel Samolysov 098afdb0a0 [ArgPromotion] Make a non-byval promotion attempt first ...

It makes sense to make a non-byval promotion attempt first and then
fall back to the byval one. The non-byval ('usual') promotion is
generally better, for example it does promotion even when a structure
has more elements than 'MaxElements' but not all of them are actually
used in the function.
