Reproduction

This code compiles on 5.9.2:

protocol P {
}

struct S: P{
}

extension S {
  static func f() -> (Self) -> (some P) {
    let fn: (Self) -> Self = { $0 }
    return fn
  }
}

This code crashes on 5.10:

Assertion failed: ((!F || opTI->isABICompatibleWith(resTI, *F).isCompatible()) && "Can not convert in between ABI incompatible function types"), function create, file SILInstructions.cpp, line 2649.
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.
