[PySide] Wrapinstance is not 64-bit safe

[Luc-Eric Rousseau]

Hello,

my team has logged the following Pyside bug:

PYSIDE-191 wrapInstance should accept 64-bit address

It causes pyside's wrapinstance to fail if an object's address is
larger than 32-bit.  This is apparently becoming more frequent under
Windows 8.

We've found a similar bug logged last August
PYSIDE-103 shiboken.wrapInstance raises OverflowError for large addresse"

We're proposing a fix in PYSIDE-191
