[Bug debug/19191] [4.0 Regression] No DWARF2 DW_TAG_inlined_subroutine entry generated

[fnf at specifixinc dot com]

I tried the patch and it does generate a entry:

  <2><cd>: Abbrev Number: 10 (DW_TAG_inlined_subroutine)
     DW_AT_abstract_origin: <5f>
     DW_AT_low_pc      : 0x80483a1
     DW_AT_high_pc     : 0x80483a6

Note though that this only covers the first instruction of the inlined
subroutine, the mov instr at 80483a1:

 080483a0 <main>:
  80483a0:       55                      push   %ebp
  80483a1:       b8 04 00 00 00          mov    $0x4,%eax
  80483a6:       89 e5                   mov    %esp,%ebp

I believe what needs to happen is for the DWARF2 DW_TAG_inlined_subroutine
entry to use the DW_AT_ranges attribute to indentify the discontiguous
address ranges of the inlined subroutine, instead of using DW_AT_low_pc and 
DW_AT_high_pc.
