It also optimizes the AST for runtime evaluation. Before, we constructed
a leftwards conditional tree (`(_a_b = (_a = a) == null ? void 0 : _a.b)
== null ? void 0 : _a_b.c`) instead of a rightward tree (`(_a = a) ==
null ? void 0 : (_a_b = _a.b) == null ? void 0 : _a_b.c`), which
required multiple `== null` checks after the first nullish is found.
