PPC: [fullcode] Switch passing of new.target to register.

Port 440a42b74135b84c188d7db11f4c07678f53d0f3

Original commit message:
    This passes the new.target value in a register instead of through a
    side-channel via the construct stub. Note that this marks the last
    consumer of said side-channel and the special slot in the construct
    stub frame can be removed as a follow-up.
