This will allow embedders to actually instantiate the {DefaultJobHandle}
as suggested in the comment. Node currently implements {PostJob()} by
just returning a nullptr. After this change, it can use the new
{NewDefaultJobHandle} function and we can actually start using this API
in v8.

The AsmParser kept pointers into ZoneVectors, which were accessed even
after those vector might have grown. For regular vectors, this would be
a use-after-free; with ZoneVectors it is technically allowed, since the
old memory stays alive. This will change with
https://crrev.com/c/2302895, which zaps zone memory which is
deallocated. Eventually, we might want to reuse large deallocations in
zone memory, hence this "use after free" needs to be fixed.

This CL fixes the issue by explicitly re-allocating in the zone instead
of using ZoneVectors. This makes sure that the old memory stays alive.
This is kind of a quick-fix, but since asm.js is more or less deprecated
anyway (in favor of Wasm), it's OK if this code does not profit from
future ZoneVector memory re-use optimizations.

Drive-by: Move field initializers to the field declaration.

The {operator==} on {VarState} did not check the spill offset, so when
merging stack states, we forgot to move stack values if both source and
destination were stack slots, but at different offsets.
This CL fixes this by removing the {operator==}, because the semantics
(and use) are not clear, and it's only used in one place anyway.
The equality check was mostly redundant, so inlining it also makes the
code smaller and faster.

SSE requires operand0 to be a register, since we don't have memory
alignment yet. AVX can have performance issues for unaligned access.

1) turn static methods to instance ones.
2) change New/Delete to NewArray/DeleteArray getting array length as
   argument instead of raw size.
3) propagate type tags through allocate/delete methods of existing
   AllocationPolicy classes.

This will allow implementing accounting of deallocated zone memory.

Replacing EnsureSweepingCompleted() with DrainSweepingWorklistForSpace()
caused sweeping to be completed later. This resulted in longer scavenger
pauses, since the scavenger had to stop & resume sweeping more often.
To avoid this, the scavenger now completes sweeping when all pages are
swept.
