[lite] Allocate feedback vectors lazily
...
Allocate feedback vectors lazily when the function's interrupt budget has
reached a specified threshold. This cl introduces a new field in the
ClosureFeedbackCellArray to track the interrupt budget for allocating
feedback vectors. Using the interrupt budget on the bytecode array could
cause problems when there are closures across native contexts and we may
delay allocating feedback vectors in one of them causing unexpected
performance cliffs. In the long term we may want to remove interrupt budget
from bytecode array and use context specific budget for tiering up decisions
as well.

Reason for revert:
[Sheriff] Breaks several layout tests, e.g.:
http://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2032/builds/1067
Several output lines change from PASS to FAIL. If the changes are intended, please land a needsmanualrebaseline change in blink first.

Fix %NeverOptimizeFunction runtime call.

The current usage of this runtime function is broken as it does not
prevent inlining of the affected function but rather bails out from the
whole unit of compilation after trying to inline affected functions.
This simplifies said runtime function to avoid accidental misuse.
