testsuite: add additional option to force DSE execution [PR103662]

This fixes a dump tree match check that is UNRESOLVED with the -O0
optimization option, as the optimization pass corresponding to the
dump file is not run at -O0, and the dump is not generated.

	PR fortran/103662

gcc/testsuite/ChangeLog:

	* gfortran.dg/unlimited_polymorphic_3.f03: Force execution of
	the DSE optimization pass.
