I noticed while testing a backport of the PR121772 fix to GCC 13 that
the test wasn't triggering the ICE as expected with the unpatched
compiler.
This turned out to be because the ICE is a checking ICE, and we
configure by default with --enable-checking=release on the branches.
Additionally, I hadn't noticed when doing the backports to 15 and 14
since there we still ICE later on in emit_move_insn even if we don't
catch the invalid gimple with checking.
I'm not too sure why the 13 branch doesn't see the emit_move_insn ICE,
but it's somewhat irrelevant - the important thing is that adding
-fchecking to the options makes the test fail as expected with an
unpatched compiler (i.e. with a gimple checking failure), even on
release branches.
I considered applying this patch to just the release branches, but
figured that trunk will at some point itself become a release branch, so
it seems to make most sense just to apply it everywhere.
I've checked that the test still passes with this patch, and still fails
if I revert the PR121772 fix.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
