However, I must admit the patch had a problem.  For some reason, I had
assumed get_callee_fndecl() was only used by the tree inliner.  I was
wrong, and that's why the decision of following DECL_ABSTRACT_ORIGIN
has caused problems in C++.  Moving that change from get_callee_fndecl
to the tree inliner fixed the C++ regressions while not re-introducing
execute/20011114-1.c (though compile/20011114-1.c, totally unrelated,
still fails, and still gets me confused as to the test results <:-)

Here's the patch, bootstrapped and regression tested on
i686-pc-linux-gnu.  Ok to install?
