Emit a call to an operator new or operator delete function, as implicitly created by new-expressions and delete-expressions.

C++1y [expr.new]p10: [In a new-expression,] an implementation is allowed to omit a call to a replaceable global allocation function.

We model such elidable calls with the 'builtin' attribute.
