a6da98d86f Introduce a new phantom weakness type without finalization callback.
Handles of this type are automatically reset by the garbage collector
when their objects are not longer reachable.

The motivation is to reduce pause time of external.weak_global_handles
phase of the garbage collector by not maintaing the list of pending
callbacks and not calling the callbacks.

Local testing on discourse page of the v8.inifinite_scroll benchmark
shows 7x improvement for this GC phase.

Before:
external.weak_global_handles
 len: 21
 min: 0.0
 max: 4.5
 avg: 0.757142857143

After:
external.weak_global_handles
 len: 21
 min: 0.0
 max: 0.5
 avg: 0.109523809524

A follow-up patch will enable the new phantom handles in Chromium.

00a589d9ff [api] Bring back finalizers on global handles
Seems like node.js depends on it in many places. At least try to get rid
of WeakCallbackData vs WeakCallbackInfo

85f32f1fc8 Don't NULL-check GlobalHandle::Node::object_
If it's Smi::FromInt(0), the NULL check would trigger. Instead, use the
handle-zap value to mean "not set".

6f472db65a Disable soon to be deprecated APIs per default for v8
Embedders still can use those APIs by default

test-api.cc still has an exception to use the old APIs...

fc0a1a709c [test] Test expectations in cctest should use CHECK and not DCHECK.
The test expectations should fail consistently in both release and debug
builds. DCHECK is only meant for debug-only checks in production code.

e5a77abcf8 Add convenience method for converting v8::PersistentBase to v8::Local
The CL addes convenienve method that allows to write code like the following
v8::Local<v8::Object> local = v8::Local<v8::Object>::New(global, isolate);
in a more readable way:
v8::Local<v8::Object> local = global.Get(isolate);

There is already v8::Eternal::Get that does similar thing.

d07a2eb806 Rename ASSERT* to DCHECK*.
This way we don't clash with the ASSERT* macros
defined by GoogleTest, and we are one step closer
to being able to replace our homegrown base/ with
base/ from Chrome.

- this avoids using relative include paths which are forbidden by the style guide
- makes the code more readable since it's clear which header is meant

bda84eaf23 Make LeakSanitizer happy, part 2. Fixed register usage on the way.
Note that according to the System V ABI for AMD64, rbx must be
preserved across calls. We actually crash with clang in the x64
assembler tests without that fix, we were lucky with GCC.
