Hi!
When adding _BitInt support I was hoping all or most of arches would
implement it already for GCC 14. That didn't happen and with
new hosts adding support for _BitInt for GCC 16 (s390x-linux and as was
posted today loongarch-linux too), we need the _BitInt support functions
exported on those arches at GCC_16.0.0 rather than GCC_14.0.0 which
shouldn't be changed anymore.
The following patch does that. Both arches were already exporting
some of the _BitInt related symbols in their specific map files, this
just moves the remaining ones there as well.
Tested on x86_64-linux (-m32/-m64, with all bitint related tests, both
normally and --target_board=unix/-shared-libgcc, additionally compared
abilists of libgcc before/after), ok for trunk?

* libgcc-std.ver.in (GCC_14.0.0): Remove bitint related exports
from here.
* config/i386/libgcc-glibc.ver (GCC_14.0.0): Add them here.
* config/i386/libgcc-darwin.ver (GCC_14.0.0): Likewise.
* config/i386/libgcc-sol2.ver (GCC_14.0.0): Likewise.
* config/aarch64/libgcc-softfp.ver (GCC_14.0.0): Likewise.
