7f331f6280 Make HCheckPrototypeMaps compatible with parallel recompilation. 
HCheckPrototypeMaps currently records the prototype and the holder of the
prototype chain (both ends of the chain) and assumes that the chain elements
and their maps did not change in during the entirety of Crankshaft. The actual
traversal of the prototype chain happens in Lithium at code generation.
With parallel compilation, this assumption is not longer correct.

0f5b5dd311 Remove GlobalHandles::number_of_weak_handles_ and number_of_global_object_weak_handles_ 
This is a preparation patch for inlining MakeWeak() and Clear().

Given that NumberOfWeakHandles() is used only by CHECK_EQ() in serialized.cc and that NumberOfGlobalObjectWeakHandles is unused, it is wasteful to keep track of number_of_weak_handles_ and number_of_global_object_weak_handles_ at every MakeWeak() and Clear(). Instead, we can count the number at the point where NumberOfWeakHandles() or NumberOfGlobalObjectWeakHandles() is called.

fab9a39d9d Make the Isolate parameter mandatory in Locker and Unlocker classes. 
Note that leaving out the Isolate parameter previously had a very special
meaning, namely "use the *default* Isolate", i.e. the one magically created at
program initialization time. All other API entries use the meaning "current
Isolate", which is different in a multi-threaded setting and confusing.

Temporarily disabled deprecations until Chrome is ready.

1074e1f558 Fix the xrange calculation of the V8 timeline plot 
Currently an xrange is calculated by V8.Execution. This would be fine for JavaScript benchmarks in which everything happens inside of V8.Execution. On the other hand, in Chrome profiling, events can happen outside of V8.Execution. To visualize such outside events, we need to calculate an xrange so that the xrange covers all events.
