Wouldn't 'u8 ret', as an additional argument be sufficient? gcc still
ought to be able to use the same register for new and ret if we remove
the early clobber.
We can't (validly) remove the early-clobber, otherwise the compiler
would be permitted to use a register also used for addressing the lock
structure for "new".

I meant for 'ret'.
