[GOOGLE] Don't update the callee count if caller is not resolved node

[Dehao Chen]

This patch changes to no update callee count if caller count is not a
resolved node (in LIPO mode) during AutoFDO compilation. This is
because AutoFDO will have the same edge counts for all unresolved
nodes. Original update method will lead to multi-update of the callee.

Bootstrapped and testing on going.

OK for google-4_8 if test is OK?

Thanks,
Dehao
