Santiago Aboy Solanes d235114325 Reland x2 "[turbofan][ptr-compr] Remove redundant ChangeTaggedToCompressed"
This is a reland of c924f54ee0

Reason: Added back a bitcast that was supposed to be redundant (but it
wasn't)

Changes can be seen from patchets 1..3.

Original change's description:
> [turbofan][ptr-compr] Remove redundant ChangeTaggedToCompressed
>
> The final goal is to eliminate it altogether. This CL just
> eliminate the redundant ones.
