This is defined only when __lp64__ is defined. That means that ulong is
64 bits long. Therefore we don't need to use a separate u64 type on those
architectures.

Fix up the code to take advantage of that, removing the preprocessor
conditions.

Changes in v2:
- Use MEM_SUPPORT_64BIT_DATA instead of a new define
