  Log Message:
  -----------
  [CodeExtractor] Preserve entire scope of !DIVariables when moving them

When a dbg.value is moved into a new function, the corresponding
variable should have its entire scope chain reparented with the new
function. The current implementation drops the scope chain and replaces
it with a subprogram for the new function.
