Eric Pouech : dbghelp: Keep compiland's address for Dwarf debug format.

[Alexandre Julliard]

Module: wine
Branch: master
Commit: 6f8ba8119ae6d40621e499d8d34d5379eccad084
URL:    https://gitlab.winehq.org/wine/wine/-/commit/6f8ba8119ae6d40621e499d8d34d537...

dbghelp: Keep compiland's address for Dwarf debug format.

Partly reverting 99eb63bd7a41b87d472bb622a5faf24d1fcd91c5
(it's still needed on Dwarf for blocks with multiple
non-contiguous address ranges).
