True if the allocation result needs to be null-checked.
C++11 [expr.new]p13: If the allocation function returns null, initialization shall not be done, the deallocation function shall not be called, and the value of the new-expression shall be null.
An allocation function is not allowed to return null unless it has a non-throwing exception-specification. The '03 rule is identical except that the definition of a non-throwing exception specification is just "is it throw()?".
