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.

--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.

Some implementations of std::lower_bound require weak-strict ordering.

The comparison operator must be assymetric, which doesn't hold for less_equals.

port 8965b683 (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.

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.
