I believe here's one part you need for the main1.C failure, which simply
aborts in cgraph_finalize_function without this patch, because
TREE_ASM_WRITTEN is set for the second function called "main()".

I think we shouldn't try to defer or expand function that have
TREE_ASM_WRITTEN set... Bootstrapped and regtested c++ on
i686-pc-linux-gnu, gives one FAIL less, 6 to go :)  OK?

All the other new regressions all seem to be caused by one more bug.

	* semantics.c (expand_or_defer_fn): Don't try to expand or defer
	functions that seem to have been written out already.
