Emit the code for deleting a single object with a destroying operator delete.
If the element type has a non-virtual destructor, Ptr has already been converted to the type of the parameter of 'operator delete'. Otherwise Ptr points to an object of the static type.

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.
