Commit Message

FFI: Fix pointer difference operation on 64 bit platforms.

Thanks to cuiweixie.

(cherry picked from commit b58b07189)

The metamethod for FFI pointer subtraction casts the result value to a
32-bit value, which leads to invalid results.

This patch removes the excess cast.

Sergey Kaplun:
* added the description and the test for the problem
