Compiler crash with pack expansion

[xAlien95]

Description
The following code is causing a compiler crash, with the error message Incorrect reconstructed type for $ss7KeyPathCyxqd__Gqd__Qp_tD (Full output/stack dump).

extension Array {
  func sorted<each Value: Comparable>(by keyPath: repeat KeyPath<Element, each Value>) -> Self {
    return sorted { a, b in
      var ordered = true, equal = true

      func process<T: Comparable>(_ keyPath: KeyPath<Element, T>) {
        let l = a[keyPath: keyPath], r = b[keyPath: keyPath]
        if equal {
          if l != r { equal = false }
          if l > r { ordered = false }
        }
      }

      repeat process(each keyPath)

      return ordered
    }
  }
}

Steps to reproduce
Build the script with the latest Swift development snapshot.

Expected behavior
The compiler shouldn't crash.

Environment

• Swift compiler version info: swift-DEVELOPMENT-SNAPSHOT-2023-07-10-a.xctoolchain, Apple Swift version 5.9-dev (LLVM 677d82daa6d87d2, Swift 291fe21d5020234)
• Xcode version info: Xcode 14.2, Build version 14C18
• Deployment target: macOS 12.6.7 (21G651)

It's actually a regression: it compiles successfully and works as intended with swift-DEVELOPMENT-SNAPSHOT-2023-07-07-a.xctoolchain.
