X87: Refactor lexical home object binding.

X87: Refactor lexical home object binding.

port 345fa142a9fca4b468417350ac26f61101d626e8 (r28802).

    port of r28769 overwrite some of r28802 so we port them again.

original commit message:

    Before this we had 3 super related lexical bindings that got injected
    into method bodies: .home_object, .this_function,  and new.target.
    With this change we get rid of the .home_object one in favor of using
    .this_function[home_object_symbol] which allows some simplifications
    throughout the code base.
