[flang] - ieee_exceptions.f90: I added all of the routines listed in table 17.3 of the standard that were not currently specified. I also re-ordered the routines to be in the same order as the standard.
- doconcurrent01.f90: I removed the custom versions of ieee_exceptions and
iso_fortran_env. I also fixed a typo in a comment. Also, the use of the real
standare interface caused one of the error messages to go away, so I fixed
that.
