Implement -fsemantic-interposition First attempt at implementing -fsemantic-interposition. Rely on GlobalValue::isInterposable that already captures most of the expected behavior. Rely on a ModuleFlag to state whether we should respect SemanticInterposition or not. The default remains no. So this should be a no-op if -fsemantic-interposition isn't used, and if it is, isInterposable being already used in most optimisation, they should honor it properly. Note that it only impacts architecture compiled with -fPIC and no pie.
