  Log Message:
  -----------
  [llvm-cxxfilt] Improve strip-underscore behavior

Summary:
For platform that uses macho format, c++filt should be stripping the
leading underscore by default. Introduce the binutil compatible "-n"
option to control strip-undercore behaivor together with the existing
"-_" option and fallback to system default if none of them are set.
