Remove duplicate tests. Use a common pattern of sanitizing, building and dumping the whole module instead of calling individual methods. There's too much internal state being tracked in the tests for my liking. Split most tests into three: * Const_* tests will check the emission of creation-time-constant expressions. * Runtime_* tests will check the emission of runtime expressions, where indexing operates with a constant index. * Dynamic_* tests will check the emission of runtime expressions, where indexing operates with a runtime index.
