[iDmitriyy]

Description

Using of ~Copyable type with async let causes compiler error

Reproduction

    struct NonCopyable: ~Copyable {}

    struct Pair: ~Copyable {
      let first: NonCopyable
      let second: NonCopyable
    }
    
    @Sendable func request() async -> NonCopyable { NonCopyable() }
    
    async let first = request()
    async let second = request()
    
    let outputs = await Pair(first: first, second: second) // ERROR: Copy of noncopyable typed value. This is a compiler bug. Please file a bug with a small example of the bug

Expected behavior

Compiler don't ask me to file a bug.
