+  Fills a target buffer with a 64-bit value, and returns the target buffer.

+  bytes of Buffer.
+
+  If Length > 0 and Buffer is NULL, then ASSERT().
+  If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().
+  If Buffer is not aligned on a 64-bit boundary, then ASSERT().
+  If Length is not aligned on a 64-bit boundary, then ASSERT().
+
+  @param  Buffer  Pointer to the target buffer to fill.
+  @param  Length  Number of bytes in Buffer to fill.
+  @param  Value   Value with which to fill Length bytes of Buffer.

+  @return Buffer.
