[PATCH] Fix c-c++-common/ubsan/pr71403-?.c testcases

[Richard Biener]

c-c++-common/ubsan is tortured, no need to specify -O3 (in fact
it's a waste of time).

Committed.

        * c-c++-common/ubsan/pr71403-1.c: Use dg-additional-options
        and remove -O3.
        * c-c++-common/ubsan/pr71403-2.c: Likewise.
        * c-c++-common/ubsan/pr71403-3.c: Likewise.
