[VM] Use redefinitions for strenghtening, prefer equality comparison over strict comparison When strenghtening the types in AOT call specializer, we do it via redefinitions instead of setting a reachingt type on the Value. This has the advantage that all uses will get the new type, which improves e.g. StaticCall(_IntegerImpl.*, v1, v1) where multiple uses can benefit. This CL also changes the AOT call specializer to prefer equality comparisons over strict comparisons, because strict comparisons can force boxing (which causes code bloat).
