[test-suite] making polybench/symm succeed with "-Ofast" and "-ffp-contract=on"
...be some tests that don't have a useful tolerance; sometimes these are badly-implemented tests, but sometimes the sensitivity represents an underling physical reality of a simulated system (there's a lot of very-interesting mathematical theory behind this, e.g. https://en.wikipedia.org/wiki/Chaos_theory#Sensitivity_to_initial_coonditions).
