Diagnostic around conforming to a protocol with a noncopyable type has no source location info

[fwcd]

Description

Some ownership-related diagnostics seem to be missing source location information. See e.g. the example below

Reproduction

protocol TypedPointer<Pointee> {
    associatedtype Pointee
    
    var pointee: Pointee { get }
}

extension UnsafePointer: TypedPointer {}

Expected behavior

I would expect the associated diagnostic:

<unknown>:0: error: 'self.pointee' is borrowed and cannot be consumed

...to have location/line information, e.g. in this case probably the line conforming UnsafePointer to the protocol.

Environment

swift-driver version: 1.115 Apple Swift version 6.0 (swiftlang-6.0.0.9.10 clang-1600.0.26.2)
Target: arm64-apple-macosx15.0

Additional information

I was a bit surprised that this broke in Swift 6, it looks like the issue is that UnsafePointer's Pointee is ~Copyable and that the interaction between noncopyable types and protocols/generics isn't good enough to let us spell out this conformance anymore: https://github.com/swiftlang/swift-evolution/blob/main/proposals/0390-noncopyable-structs-and-enums.md#declaring-noncopyable-types

@fwcd there is a good first issue which i am working on rn and i found its related to Diagnostics so is there any way i can also look into this one
this is the issue
