Once we crankshaft a method, we should turn off allocation site info for

CPU profiler should support names of accessors set via v8::Object::SetAccessor

This change fixes the case when the accessors are invoked from JSObject::{Get,Set}PropertyWithCallback.

It already works for inlined calls generated by StoreStubCompiler::CompileStoreCallback. The same still needs to be fixed for getter invocations generated by BaseLoadStubCompiler::CompileLoadCallback, corresponding case is commented out in the new test.

This is a slightly modified version of r14915 which was rolled back due to test timeout on Windows. Compared to r14915 the new tests use OS::TimeCurrentMillis instead of OS::Ticks as OS::Ticks has ms precision on Windows and trying to wait 10 ticks (us) will result in at least 1 ms pause.
