structs: optimize struct creating functions.

We reduce consing in the structure instantiating API.

* struct.c (make_struct_impl): New static function, formed
from make_struct. This takes two "struct args *" arguments,
for both the slot/pair property list and the BOA list.
(make_struct): Now a wrapper for make_struct_impl.
(struct_from_plist): Call make_struct_impl instead of
make_struct, avoiding the args_get_list operation that
potentially conses args on the stack into a list.
Diagnosis is improved because make_struct_impl takes a self
argument.
(struct_from_args): Call make_struct_impl instead of
make_struct.
