It is a softer version than chromium's landmines script, as

ES6 collections: Fix order of constructor logic

The adder should be gotten before the iterator.

Motivation: Once this is done we should be able to use a for-of loop
instead which leads to cleaner code and correct behavior once the
for-of loop correctly supports abrupt completion.

CpuProfiler: eliminate cpu-profiler dependency from heap-inl.h

We accessed to cpu_profiler for tracking SharedFunctionInfo objects movements and used their addresses for generating function_id. Actually we could replace the manually generated shared_id by the pair script_id + position. In this case we can drop SharedFunctionInfo events support from cpu_profiler and remove the dependency.

BTW GetCallUid was used as an unique identifier of the function on the front-end side. Actually it is a hash which might not be unique. So I renamed GetCallUid with GetHash and implemented GetFunctionId method.
