This seems to have been a transient build failure caused by:

    Add Trait Resolver simple type-path lookup
    
    Post type checking we need to be able to lookup trait references, but do
    not need to resolve the trait with error messages. We simple want to look
    it up if it exists.

But resolved by the next commit:

    Add impl-trait path probe helper
    
    This adds a probe to lookup candidates for a segment for any impl block
    for this receiver and trait. This simplifies some query based compilation
    code. When the item is resolved to a trait item but might be overriden by
    a reciever impl block instead.

Not all buildbot workers have finished building all the latest commits though.

Cheers,
