Previously, if we typechecked a statement like var x bool = p1.f == p2.f && p1.g == p2.g we would correctly update the '&&' node's type from 'untyped bool' to 'bool', but the '==' nodes would stay 'untyped bool'. This is inconsistent, and caused consistency checks during walk to fail. This CL doesn't pass toolstash because it seems to slightly affect the register allocator's heuristics. (Presumably 'untyped bool's were previously making it all the way through SSA?) Fixes #23414.
