[DebugInfo] Avoid applying a misleading cleanup loc in case blocks

Switch cases without a trailing curly brace have ambiguous cleanup
locations. Here's what the current stepping behavior looks like:

  switch x {
    case ...:
      if true { foo() } // Step
      else    { bar() } // Step
  }

The second step can be misleading, because users might think that the
else branch is taken.
