    IPA ICF + ASAN: do not merge vars with different alignment

    gcc/ChangeLog:

            PR sanitizer/99168
            * ipa-icf.c (sem_variable::merge): Do not merge 2 variables
            with different alignment. That leads to an invalid red zone
            size allocated in runtime.

    gcc/testsuite/ChangeLog:

            PR sanitizer/99168
            * c-c++-common/asan/pr99168.c: New test.
