So the problem here is EXPAND_INTER_MACRO_16 expands to nothing if 16 byte FP does not
exist but we still add a comma after it and that causes a build failure.
The same is true for EXPAND_INTER_MACRO_10 too.
Committed as obvious after a bootstrap and test on x86_64-linux-gnu and aarch64-linux-gnu.

PR libfortran/110759
* ieee/ieee_arithmetic.F90
(COMP_INTERFACE): Remove the comma after EXPAND_INTER_MACRO_16
and EXPAND_INTER_MACRO_10.
(EXPAND_INTER_MACRO_16): Add comma here if 16 byte fp exist.
(EXPAND_INTER_MACRO_10): Likewise.
Those operations were added to Fortran 2018, and correspond to
well-defined IEEE comparison operations, with defined signaling
semantics for NaNs. All are implemented in terms of GCC expressions and
built-ins, with no library support needed.

The IEEE_MODES_TYPE type and the two functions that get and set it
were added in Fortran 2018. They can be implemented using the already
existing target-specific functions. A future optimization could, on
some targets, set/get all modes through one or two instructions only,
but that would need a new set of functions in all config/fpu-* files.

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.

I moved the library implementation of IEEE_VALUE in libgfortran from

The FE converts the old school .eq. to ==,
and then tracks the ==. The module starts with == and so it does not
properly overload the .eq. Reversing the interfaces fixes this.
