Subject: [PATCH] Fortran: add IEEE_QUIET_* and IEEE_SIGNALING_* comparisons

Hi,
This is a repost of the patch at https://gcc.gnu.org/pipermail/gcc-patches/2022-September/600887.html
which never really got green light, but I stopped pushing because stage 1 was closing and I was out of time.
It depends on a middle-end patch adding a type-generic __builtin_iseqsig(), which I posted for review at: https://gcc.gnu.org/pipermail/gcc-patches/2023-June/620801.html
Bootstrapped and regtested on x86_64-pc-linux-gnu, OK to commit (once the middle-end patch is accepted)?

Subject: [PATCH 2/2] Fortran: add IEEE_QUIET_* and IEEE_SIGNALING_*
comparisons
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.
gcc/fortran/
* f95-lang.cc (gfc_init_builtin_functions): Add __builtin_iseqsig.
* trans-intrinsic.cc (conv_intrinsic_ieee_comparison): New
function.
(gfc_conv_ieee_arithmetic_function): Handle IEEE comparisons.
gcc/testsuite/
* gfortran.dg/ieee/comparisons_1.f90: New test.
* gfortran.dg/ieee/comparisons_2.f90: New test.
libgfortran/
* ieee/ieee_arithmetic.F90: Add IEEE_QUIET_* and
IEEE_SIGNALING_* functions.
