On leon3-elf and presumably on other targets, the test fails due to
differences in calling conventions and other reasons, that add extra
gimple stmts that prevent the expected optimization at the expected
point. The optimization takes place anyway, just a little later, so
tolerate that.
Regstrapped on x86_64-linux-gnu, also tested with gcc-14 targeting
leon3-elf. Ok to install?

* gcc.dg/tree-ssa/pr108357.c: Tolerate later optimization.

More tolerance and less prejudice are key for inclusion and diversity
Excluding neuro-others for not behaving ""normal"" is *not* inclusive
