testcase: Add testcase for already fixed PR [PR118476]

Browse source 
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.
