    M llvm/lib/DebugInfo/Symbolize/DIPrinter.cpp
    A llvm/test/tools/llvm-symbolizer/discriminator.test

  Log Message:
  -----------
  Print discriminators when printing .debug_line in GNU style.

Summary:
gnu addr2line prints DWARF line table discriminators like so:

<file>:<line> (discriminator <Number>)

This matches that behavior.

Document how and when --output-style=GNU prints discriminators

Add test for new GNU-style discriminator printing.
