  This testcase was fixed by r15-3052-gc7b76a076cb2c6ded but is
a testcase that failed in a different fashion and a much older
failure than the one added with r15-3052.

Pushed as obvious after a quick test.

	PR tree-optimization/118476

gcc/testsuite/ChangeLog:

	* gcc.dg/torture/pr118476-1.c: New test.

Signed-off-by: Andrew Pinski <quic_apinski@quicinc.com>
(cherry picked from commit d45a6502d1ec87d43f1a39f87cca58f1e28369c8)
