debug/9864: [3.2/3.3/3.4 regression] Fortran ICE in dwarf2out:add_abstract_origin_attribute with -g -O -finline-functions

[Volker Reichelt]

Here's an even shorter testcase without all the warnings (which still ICEs):

-----------------------snip here------------------------
      SUBROUTINE FOO
      CALL BAR
      END

      SUBROUTINE BAZ
      ENTRY BAR
      CALL QUUS
      END
-----------------------snip here------------------------

Volker
