A new regression from the inlining fix

Jason,

The inline fix in toplev.c causes g++.jason/2371.C to fail, with log:

It looks to me like my patch has uncovered an inlining issue
elsewhere.  It appears that something is getting tree inlined and not
put in the object file when it should be, or a reference to it is not
being removed when it should be.  Or maybe the test requires extra
flags?

Anyway, I have no idea how to fix this.  Do you want me to revert the
toplev.c fix?  It looked (and looks) OK to me.

Neil.
