[GOOGLE] Use resolved node during AFDO vpt

[Teresa Johnson]

AFDO invokes cgraph_node_for_asm during VPT to get the cgraph node for
a callee. Use the resolved node so we don't add a reference to the
un-resolved node after LIPO fixup.

Passes regression tests and internal test. Ok for google/4_9?

Thanks,
Teresa
