Issue Description:

This code compiles:

import SwiftUI
struct GaugeSample: View {
 var body: some View {
  Gauge(value: 7, in: 0...10) {
   Text("Label")
  } currentValueLabel: {
   Text("7")
  } minimumValueLabel: {
   Text("0").foregroundColor(.red)
  } maximumValueLabel: {
   Text("10").foregroundColor(.green)
  }
 }
}

But if I try to extract the view from either minimumValueLabel or maximumValueLabel I get "Failed to produce diagnostic for expression"

import SwiftUI
struct GaugeSample: View {
 var body: some View {
  Gauge(value: 7, in: 0...10) {
   Text("Label")
  } currentValueLabel: {
   Text("7")
  } minimumValueLabel: {
   ExtractedView()
  } maximumValueLabel: {
   Text("10").foregroundColor(.green) 
  }
 }
}
struct ExtractedView: View {
 var body: some View {
  Text("0").foregroundColor(.red)
 }
}

It is unique to minimumValueLabel and maximumValueLabel. Extracting out the view from currentValueLabel does not cause this error.
