Niels Sascha Reedijk 92b3138b83 Import GCC 13.1.0 and dependencies
Updated dependencies:
 * GMP 6.2.1
 * ISL 0.24
 * MPL 1.2.1
 * MPFR 4.1.0

The dependencies were pulled in by running the ./contrib/download_prerequisites script and then
manually removing the symbolic links and archives, and renaming the directories (i.e mv isl-0.24 to isl)

In general, merging process should not be very difficult, but we need to
track GCC-specific patches carefully. Here is a general list of actions
required to perform the merge:
* Checkout recent GCC tree.
* Run merge.sh script from the libffi directory.
* Add new files and remove old files if needed.
* Apply all needed GCC-specific patches to libffi (note that some of
them might be already included to upstream). The list of these patches
is stored into LOCAL_PATCHES file. May need to re-run autogen.sh to
regenerate configure and Makefile.in files.
* Send your patches for review to GCC Patches Mailing List (gcc-patches@gcc.gnu.org).
* Update LOCAL_PATCHES file when you've committed the whole patch set with new revisions numbers.
