3414a514cd Fixed test failure. 
A test case erroneously expected a transition to a double array, but the array remains FAST_SMI.

In person LGTM from Danno...

d7d917e6f0 Out of bounds memory access in TestJSArrayForAllocationSiteInfo. 
The function intended to check the map pointer of an AllocationSiteInfo object, but neglected to
subtract an offset to do so.

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.

f6659cfcd7 Recently I tried to debug CPU profiling on Chrome. 
I've found that profiling is not working in Debug version.
The actual problem is that sandbox/playgroung configuration is wrong and tgkill syscalls are disallowed.

This patch will make such cases more clear.

f15f294127 Sync laziness between BuildFunctionInfo and MakeFunctionInfo.

MakeFunctionInfo does not check for debug break points.

This fixes a regression introduced in r11866.
