Subject: Account for devirtualization opportunities in inlining heuristics

Jan,

Here are the testcases for inlining improvements we've discussed on IRC a couple of days ago.

Current mainline handles inline-devirt-1.C and inline-devirt-5.C cases.  With my w-i-p patches to teach inlining heuristics about devirtualization opportunities (also attached) inline-devirt-2.C, inline-devirt-3.C are also fully optimized.

Let me know if you have suggestions for tackling the other cases.

Do you think committing the testcases mainline, XFAIL'ed as necessary, would be useful?

Thanks,
