ICE: rustc stack overflow error w/ recursive types

Given the following code:

trait Stream<T, N: Stream<T>> {
}

pub fn main() {
    println!("zomg");
}

Running rustc gives the following output:

task 'rustc' has overflowed its stack
[1]    47380 illegal hardware instruction  rustc types.rs

cc me

this is probably a dup of some other bug. The root cause is that we put need to convert the list of bounds at the same time as processing the trait definition. As part of my branch for generalized where clauses I've changed how this works, which ought to circumvent this error -- I'm not sure what's a shorter term fix.

Duplicate of #15477?

Closing as a dupe of #15477. Thanks for filing!
