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

This reverts commit 5b44ba0e.

Reason for revert: Layout tests:
https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2064/builds/16841

Original change's description:
> (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.
