PowerPC64 support in safe_address function

[ghost]

Add a ppc64-specific implementation of the safe_address function with overflow
checking.

[laruence]

Hmm, I don't have a PowerPC64, someone can review this? or should we just commit it?

[datibbaw]

Please use one of the zend_error_ functions here.

@vitordelima could you please fix the problems?

[ghost]

Sure, I will take a look at it.
