vim-patch:7.4.1975

Problem:    On MS-Windows large files (> 2Gbyte) cause problems.
Solution:   Use "off_T" instead of "off_t".  Use "stat_T" instead of "struct
            stat".  Use 64 bit system functions if available.  (Ken Takata)

https://github.com/vim/vim/commit/8767f52fbfd4f053ce00a978227c95f1d7d323fe

Only the off_T changes are relevant, since all the "struct stat" usage
is abstracted by libuv.
