RuboCop::Cop::Lint::ShadowedArgument#assignment_without_argument_usage

Find the first argument assignment, which doesn't reference the
argument at the rhs. If the assignment occurs inside a branch or
block, it is impossible to tell whether it's executed, so precise
shadowing location is not known.
