New modref/ipa_modref optimization passes

[Jan Hubicka]

Hi,
I am slowly getting finished with the fn spec changes on trunk and then
would like to proceed with modref.  Sadly  still get the assumed_type
failuere and in addition to that:
FAIL: gfortran.dg/finalize_25.f90   -O2  execution test

I wonder if there is any chance to get Fortran FE fixed here?
