Someone has caused regressions in gfortran

[Steve Kargl]

Someone has committed a patch that is causing both
gfortran.dg/do_3.F90 and gfortran.dg/c_char_tests.f03
to fail at -O3 on amd64-*-freebsd.  A quick inspection
of fortran/ChangeLog doesn't yield a pointer to any
particular commit.  This may be caused by some middle-end
change, but I won't have time to narrow down the 
revision until later tonight.
