This relands commit df204288 with the
addtional fix to Haddps to enable SSE3 scope.

There are a couple more left in some i64x2 ops, but those are not in the
proposal, so I've left them as it is.

In production, the debug side tables will always be produced with
Liftoff in debug mode ({CompilationEnv::debug} being set).
Thus, this CL switches the tests to also test this configuration.

For keyed stores we recompute handlers when we see a new map so that
we could transition to the most general elements kind we have seen so
far. When recomputing these handlers we drop the deprecated maps.
Instead we could TryUpdate deprecated maps. This would be inline with
what TurboFan does and also may be better for performance.

The two refactorings are somewhat orthogonal, but intersect at the
class and instance type list generation, which is why it's easier to
put them in one CL.

For the removal of HasIndexedField, the removal is motivated by the
fact that is no longer necessary, and that using a flag to store this
kind of information is hacky.

For the class list changes, this is a cleanup in that we no longer
generate third-order macros, but instead normal macro lists.
There is a functional change and bug-fix in that we no longer include
abstract classes in lists that refer to instance types or maps. It's
still somewhat broken though, so I can't test abstract internal classes
yet, though. Coming in a follow-up CL.

The macro magic used to assemble the operator cache in
machine-operator.cc was quite involved and difficult to follow.
This change replaces many macros with templates and simplifies the
logic. Similar changes could also be applied to other operator builders.

Debugging with multiple isolates involved is known to be broken. Thus
skip another test which flakes currently.
