NPN_Construct allows a NPObject to be called as a construct. For example, the
test case
var s = new app.Packages.java.lang.Integer(5);
app.Packages.java.lang.Integer is a NPObject, and it implements NPN_Construct.
This fix allows a JSObject created by an API function be called as a construct
if it can be called
as a function. This is done by generating the same code for
var s = new app.Packages.java.lang.Integer(5); as
var s = app.Packages.java.lang.Integer(5);
and the caller handles both case correctly. A more sophiscated fix is to one
extra JSConstructCall
frame and allow CallAsConstructor in Builtin::HandleApiCallAsFunction.
This change itself shouldn't affect the semantic of normal case such as:
var a = {};
var s = new a();
A TypeError exception will be thrown in CALL_NON_FUNCTION (runtime.js).
Another part of fix is in the binding code, V8NPObject, which makes
NPN_InvokeDefault or NPN_Construct
call depending on which function is available.

stack pointer to change by more than one in a corner case. If we push
a constant smi larger than 16 bits, we push it via a temporary
register. Allocating the temporary can cause a register to be spilled
from the frame somewhere above the stack pointer.
As a fix, do not use pushes to materialize ranges of elements of size
larger than one.
