The test fails everywhere, e.g. because main doesn't have return type.
Here is what I have committed as obvious for it, tested on x86_64-linux
-m32/-m64, and tested with your ipa change reverted to see the ICE in those
cases.

* g++.dg/torture/pr95548.C: Change from dg-do compile to dg-do link,
add return type for main, for __SIZEOF_INT128__ test with __uint128_t
enumerator constants and add a test with unsigned long long
enumerators for all targets.
