PPC/s390: Record call counts also for megamorphic calls.

Port: 2ab3fcf42f0cf04896b26bf23bc3809d8835fd39

Original commit message:

	To make better inlining decisions, it's good to have call
counts for poly/mega-morphic cases. This CL makes it work for calls,
and another will follow to better unify the code between constructor
calls and normal calls (and thence, to record megamorphic call counts
there as well).
