According to the style guide, the implicit conversion of any number of
registers to a LiftoffRegList should not be there. This CL removes it,
and fixes two subideal call sites to use SpillRegister (receiving a
single register) instead of SpillOneRegister (receiving a register list
to choose from).

Plus some semantics-preserving rewrites.

In the previous implementation, functions overwrote any budget
decrements caused by recursive invocations of themselves, which
could cause tier-up decisions for certain unlucky functions to
get delayed unreasonably long.
This patch avoids this by working with the on-instance value
directly instead of caching it in a stack slot. That generates
the same amount of Liftoff code as the status quo, but handles
recursive functions properly.
The "barista3" benchmark's peak performance improves by almost 20%.

In addition to checking that a node is owned, CanCover() also needs to
check if there are any side-effects in between the current node and
the merged node. When merging inputs of inputs, this check was done
with the wrong side-effect level of the in-between node.
We partially fixed this before with `CanCoverTransitively`.
This CL addresses the issue by always comparing to the side-effect
level of the node from which we started, making `CanCoverTransitively`
superfluous.

This enables the --freeze-flags-after-init flag globally. Note that
tests, fuzzers, Node and other still explicitly disable the flag. The
chrome renderer process and default d8 execution will have it enabled
though.

This reverts commit 8325f86d.

Reason for revert: Speculative revert for chromium:1336850.

Original change's description:
> [heap] Sweep code pages on the background thread
>
> We already make code pages writable & executable for concurrent
> Sparkplug. We can use the same mechanism for sweeping of code pages on
> the background thread, instead of scheduling incremental tasks on the
> main thread. This allows us to remove almost all special
> handling for code pages in the sweeper and allows us to off-load more
> work from the main thread.
