review(XS): 7096639: Tiered: Incorrect counter overflow handling for inlined methods

[Igor Veresov]

 Currently inlined methods at compile levels 2 and 3 never generate invocation events (only back branch events). This could lead to unhandled invocation counter overflows in case an inlinee is never called as a separate method. The fix is to call back into the runtime to report the inlinee invocation event but do so very infrequently, since we only need this to handle overflows rather than drive the policy.
