Mohamed A. Bamakhrama 15ec302095 Define S_IREAD|IWRITE macros using IRUSR|IWUSR 
On platforms such as Android, legacy macros are no longer defined.
Hence, we define them in terms of the new POSIX macros if the new ones are defined. Otherwise, we throw an error.

coastalwhite fe3b5bf5fe chore: `__builtin_popcount` to replace BitCount8 
This replaces all occurrences of the `BitCount8` static array with the
`__builtin_popcount`. It is a rather simple and small PR.

Fixes #308.
