> This commit eliminates the global new/delete overrides that were causing
> compatibility problems (the Allocators.(h/cpp/inl) files have been
> completely removed). The GPOS `New()` macro is retained and works the
> same way, but has been renamed `GPOS_NEW()` to avoid confusion and
> possible name collisions. `GPOS_NEW()` works only for allocating
> singleton objects. For allocating arrays, `GPOS_NEW_ARRAY()` is
> provided. Because we no longer override the global delete,
> objects/arrays allocated by `GPOS_NEW()` and `GPOS_NEW_ARRAY()` must now
> be deleted by the new functions `GPOS_DELETE()` and
> `GPOS_DELETE_ARRAY()` respectively. All code in GPOS has been
> retrofitted for these changes, but Orca and other code that depends on
> GPOS should also be changed.
> Note that `GPOS_NEW()` and `GPOS_NEW_ARRAY()` should both be
> exception-safe and not leak memory when a constructor throws.
