testsuite: Add testcases for part of PR 103660

IOR part of the bug report was fixed by r13-4620-g4d9db4bdd458 but
that added only aarch64 specific testcases. This adds 4
generic testcases for this to check to make sure they are optimized.
The C++ testcases are the vector type versions.

	PR tree-optimization/103660

gcc/testsuite/ChangeLog:

	* g++.dg/tree-ssa/pr103660-0.C: New test.
	* g++.dg/tree-ssa/pr103660-1.C: New test.
	* gcc.dg/tree-ssa/pr103660-0.c: New test.
	* gcc.dg/tree-ssa/pr103660-1.c: New test.
