This adapts JSCallConstruct nodes to represent both, ordinary 'new'
constructor calls as well as 'super' constructor calls. Note that we
still bailout for super calls for now.

If we do it too early, we might get a constant pool between the reloc info
and the actual slot.

--debug-code causes full-codegen on arm64 to emit different number
of calls, which confuses the debugger when on-stack replacing code
with recompiled debug version on-stack.

The new implemtation counts the number of calls (or continuations)
before the PC to find the corresponding PC in the new code.

Several users of kKindSpecificFlags1Offset (aliased as kFullCodeFlags) were
reading/writing bytes -- not endian agnostic.

Some implementations of std::lower_bound require weak-strict ordering.
The comparison operator must be assymetric, which doesn't hold for less_equals.

port 8965b683ce (r29561)
original commit message:
Break point at calls are currently set via IC. To change this, we
need to set debug break slots instead. We also need to distinguish
those debug break slots as calls to support step-in.
To implement this, we add a data field to debug break reloc info to
indicate non-call debug breaks or in case of call debug breaks, the
number of arguments. We can later use this to find the callee on the
evaluation stack in Debug::PrepareStep.

original commit message:
We actually need round to zero truncation to implement the counterpart
of LDoubleToI in TurboFan, which tries to convert a double to an integer
as required for keyed load/store optimizations.
Drive-by-cleanup: Reduce some code duplication in the InstructionSelector
implementations.

original commit message:
- Add a TurboFanIC class, derived from TurboFanCodeStub, that
automatically distinguishes between versions of the IC called from
optimized and unoptimized code.
- Add appropriate InterfaceDescriptors for both the versions of the
stub called from unoptimized and optimized code
- Change the MathFloor TF stub generator to output either the
for-optimized or for-unoptimized version based on the minor_key
parameter.

multithreaded code.
* Fix thread leak when Worker.terminate() is not called.

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.

Note that there are currently no objects that require a pre-allocated
properties backing store, all such slots are in-object properties from
the begining. Hence {unused + pre_allocated - inobject == 0} holds.

This also adds a script to the tools directory that allows to grep for
unused bailout reasons. For now the script needs to be run manually.
