Use getSubroutineName() to the the subrouting name; this function knows
how to handle cases when DW_TAG_subprogram refers to an earlier
declaration:

0x00000050:     DW_TAG_subprogram

  DW_AT_linkage_name    ("_ZN1A1fEv")
  DW_AT_name    ("f")

...
0x00000067:   DW_TAG_subprogram

  DW_AT_low_pc    (0x0000000000000000)
  DW_AT_high_pc   (0x0000000000000020)
  DW_AT_specification     (0x00000050 "_ZN1A1fEv")

...
0x0000008c:     DW_TAG_variable
