I moved the library implementation of IEEE_VALUE in libgfortran from
Fortran to C code, which gives us access to GCC's built-ins for NaN generation
(both quiet and signalling). It will be perform better than the current
Fortran implementation.
libgfortran/ChangeLog:
PR fortran/82207
* mk-kinds-h.sh: Add values for TINY.
* ieee/ieee_arithmetic.F90: Call C helper functions for
IEEE_VALUE.
* ieee/ieee_helper.c: New functions ieee_value_helper_N for each
floating-point type.

The logic for detection of REAL(KIND=16) in kinds-override.h made
assumptions:
-- if real(kind=10) exists, i.e. if HAVE_GFC_REAL_10 is defined,
then it is necessarily the "long double" type
-- if real(kind=16) exists, then:
* if HAVE_GFC_REAL_10, real(kind=16) is "__float128"
* otherwise, real(kind=16) is "long double"
This may not always be true. Take the aarch64-apple-darwin port,
it has double == long double == binary64, and __float128 == binary128.
We already have more fine-grained logic in the mk-kinds-h.sh script,
where we actually check the Fortran kind corresponding to C’s long
double. So let's use it, and emit the GFC_REAL_16_IS_FLOAT128 /
GFC_REAL_16_IS_LONG_DOUBLE macros there.
libgfortran/ChangeLog:
* kinds-override.h: Move GFC_REAL_16_IS_* macros...
* mk-kinds-h.sh: ... here.
Commit fef67987cf changed the
libgfortran build process to generate multilib-specific versions of
ISO_Fortran_binding.h from a template, by running gfortran to identify
the values of the Fortran kind constants C_LONG_DOUBLE, C_FLOAT128,
and C_INT128_T. This caused multiple problems with search paths, both
for build-tree testing and installed-tree use, not all of which have
been fixed.
This patch reverts to a non-multilib-specific .h file that uses GCC's
predefined preprocessor symbols to detect the supported types and map
them to kind values in the same way as the Fortran front end.

ISO_Fortran_binding.h had many incorrect hardwired kind encodings in
the definitions of the CFI_type_* macros. Additionally, not all
targets support all the defined type encodings, and the Fortran
standard requires those macros to have a negative value.
This patch changes ISO_Fortran_binding.h to use sizeof instead of
hard-coded sizes, and assembles it from fragments that reflect the
set of types supported by the target.
