The semantics of the %_CallFunction intrinsic seem to be very unclear,
which resulted in a lot of bugs. Especially the combination with
%IsSloppyModeFunction is always a bug, because the receiver would be
wrapped in the wrong context. So the %IsSloppyModeFunction helper is
gone now, and many of the buggy uses of %_CallFunction are also
eliminated.
If you ever need to call something with a different receiver, then
%_Call is your friend now. It does what you want and implements the
call sequence fully (and correct).

Since the constructor is also the class object itself, allowing it to
retroactively become a strong object would have unintuitive consequences
wrt the strength of the other functions of the class, and whether instances
would be considered instances of a strong class.

TC39 agreed to disallow "use strict" directives in function body when
non-simple parameter lists are used.
This is a continuation of caitp's CL https://codereview.chromium.org/1281163002/
with some refactorings removed for now.
Still TODO: there is a lot of duplication between the is_simple field of
FormalParametersBase and the NonSimpleParameter property ExpressionClassifier
keeps track of. It should be possible to remove the former with a minor
refactoring of arrow function parsing. This will be attempted in a follow-up CL.

Also check whether the arguments count is smaller than the number of
required parameters which is the same as the SharedFunctionInfo length.

The functions of strong classes are born non extensible. But, when
the class is created we need to add an own private symbol representing
the [[HomeObject]] slot in the spec.
Like for the hidden_string property, we allow adding private own
symbols to non extensible objects.
