Undefined attribute macros have no proc macro definition, which results
in a failing `rust_assert`. This changes that assert to an if statement,
that returns early if there is no proc macro definition. Fixes #3661.

Argument position impl traits are simply syntatic sugar for generics. This
adds a new desugar pass to do this. So for example:
fn foo(a: impl Value, b: impl Value) -> i32
Is desugared into:
fn foo<T: Value, U: Value> (a: T, b: U) -> i32
So it just works like any normal generic function. There are more complex cases such as:
fn foo(_value: impl Bar<Baz = impl Foo>) -> i32
Which has a generic argument binding which needs to be turned into a where constraint:
fn foo<T, U>(_value: T) -> i32
where
T: Bar<Baz = U>,
U: Foo,

to retrieve the last "real" segment depending on the namespace.
* resolve/rust-forever-stack.h: Add new function prototype.

Set declared name according to the selected segment, if there is a self
suffix in the use declaration then select the previous segment.
