[flang] Rework read/write permission management for runtime file opening

Authored by klausler on Jul 17 2020, 11:27 AM.



Anonymous Fortran unit files (e.g., "./fort.7") need to be created
O_RDWR so that they can be written, rewound, and read. Other
files opened with no ACTION= specifier need to set read/write
permissions based on the file, if it exists.
