[es6] Throw TypeError for computed static prototype property name
The prototype of a class constructor function is read only. When we set
computed property names we were ignoring this and we were overriding the
property.
Since the prototype is the only possible own read only property on the
constructor function object we special case this so we do not have to
check this for every property in the class literal.

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.

Parsing: Make Scope not know about Isolate.
Scope, like Parser, must be able to operate independent of Isolate and the V8
heap (for background parsing). After the heap-independent phase, there is a heap
dependent phase, during which we do operations such as scope anaylysis.
This CL makes the phases explicit by not telling Scope about the Isolate too
early (during the heap-independent phase, Scope should know nothing about
Isolate). This decreases the probability of accidental code changes which would
add heap-dependent operations into the heap-independent phase.

The object literal checker now only checks for duplicate __proto__ fields in

The class literal checker checks for duplicate constructors, non constructor
