This change replaces calls to SBFrame.GetFunctionName() with
SBFrame.GetDisplayFunctionName() which can return much more user
friendly names in some cases, particularly for Swift code.

A trivial example:

main.swift

  class Doer {
      static func doTheThing() {
          print("Hello World!")
      }
  }
  Doer.doTheThing()

lldb

  (lldb) script lldb.debugger.GetSelectedTarget().GetProcess().GetSelectedThread().GetSelectedFrame().GetDisplayFunctionName()
  'static Doer.doTheThing()'
  (lldb) script lldb.debugger.GetSelectedTarget().GetProcess().GetSelectedThread().GetSelectedFrame().GetFunctionName()
  'static main.Doer.doTheThing() -> ()'
