When setting up the initial map for a (class or function) constructor,
we always over-allocate a bunch of in-object properties, in case not
all property assignments happen as `this.prop = val` assignments in
the constructor. However this over-allocation was a bit too aggressive
and added a slack of 8 to each class constructor (plus a minimum of
two, when there was no `this.prop = val` assignment). So in total this
would yield an object with initially 40 in-object property slots in
case of a simple class hierarchy like this:
```js
class A {};
class B extends A {};
class C extends B {};
class D extends C {};
new D;
```
While the slack tracking takes care of eventually shrinking the objects
to appropriate sizes, this aggressive over-allocation is still going to
hurt performance quite a bit in the beginning, and will also lead to
more traffic on the minor GC for now good reason.
Instead of the above, we now allocate a minimum of 2 in-object
properties per class (in a hierarchy) and then add a slack of 8 in the
end. Meaning for the example above we end up with 16 initial in-object
property slots, which seems sensible.

Chrome now has a googletest version that supports _TEST_SUITE_ macros
instead of _TEST_CASE_, so this CL cleans up some of the outdated usage.
