Specifically, the following changes:
1) A union that includes a dictionary and is the last non-optional
argument must actually be marked optional, just like a dictionary
argument.
2) Disallow a union from containing both a nullable type and a dictionary.
3) Now all non-Date and non-RegExp objects can be used as dictionaries,
including from overload resolution and union conversion.
We don't support dictionaries inside unions yet, or unions as
distinguishing args, so the spec changes to do with converting null to
dictionaries inside a union or picking the union overload if there is
a union containing a dictionary and null is the distinguishing arg
value are not relevant to us so far.
Unforgeable attributes are defined directly on the object, not on the
prototype. So we keep them in a separate spec array and define them
during object creation as needed.
This means that we have to pass that separate spec array to the Xray
helpers, unfortunately, which somewhat complicates those.
We mark constructors as static in the parser because they are. This
allows us to just use the isStatic() for the IDLMember to mark our
declarations static.
To generate an example interface implementation, just "make
interfacename-example" in $objdir/dom/bindings. This will place files
called interfacename-example.h and interfacename-example.cpp in that
directory. For example, "make XMLHttpRequest-example" will get you
$objdir/dom/bindings/XMLHttpRequest-example.h and
$objdir/dom/bindings/XMLHttpRequest-example.cpp.
Attribute getters currently default to const methods, while setters
and operations default to non-const methods.

There are several parts here:
1) Enforce the requirement that dictionary arguments not followed by a required argument are optional.
2) Make dictionaries no longer be distinguishable from nullable types.
3) Disallow dictionaries or unions containing dictionaries inside a nullable type.
4) Force optional dictionaries to have a default value of null so that codegen doesn't have to worry about dealing with
optional arguments that have no default value in the IDL but need to be treated as if they were null.
