Fortran: F2018 rounding modes changes
Add the new IEEE_AWAY rounding mode. It is unsupported on all known
targets, but could be supported by glibc and AIX as part of the C2x
proposal. Testing for now is minimal.
Add the optional RADIX argument to IEEE_SET_ROUNDING_MODE and
IEEE_GET_ROUNDING_MODE. It is unused for now, because we do not
support radices other than 2.
