This commit allows permission bits higher than 0o777 to go through the API (e.g. `S_ISVTX`=`0o1000`, `S_ISGID`=`0o2000`, `S_ISUID`=`0o4000`). Also documents that these bits are not exposed through `fs.constants` and their behaviors are platform-specific, so the users need to use them on their own risk.
