  Log Message:
  -----------
  [Propeller] Do not generate the BB address map for empty functions.

Empty functions (functions with no real code) are irrelevant for propeller optimizations and their addresses sometimes conflict with other functions which obfuscates the analysis.
This simple change skips the BB address map emission for such functions.
