Auto merge of #15288 - alibektas:15143, r=lnicola
Handle TyAlias in projected_ty
First of all I still have no idea how MIR works but #15143 has been an issue that constantly made RA crash so I have been looking for a way to make RA stop panicking. I have zero claims that what I want to merge has any sense or is correct :smile: but there isn't any more panicking. Even if it is wrong may this be at least a step towards resolving this issue.
As is customary this PR fixes #15143
