(Reland) [parser] moved load property position after dot

Currently LdaNamedProperty bytecode for expressions like a.b has position before dot. This CL moves this location after dot.
It's important for later removing of Nop bytecodes in expressions like a.b() where a is local variable, property call and property load should have the same position.
