Add more C++ support in gengtype.

This patch combines the changes from
http://gcc.gnu.org/ml/gcc-patches/2012-08/msg02016.html with other
additions to support C++ inside GTY'd structures.

The main changes wrt Aaron's original patch are:

- Support for function declarations inside classes.

- Support scoping in identifiers.  This does not mean that gengtype
  supports scopes, it just knows that 'Foo::id' is a single entity.

- Explicit non-support for typedef and enum inside class/struct.
  Since gengtype does not really know about scopes, it cannot
  understand these types, but it knows enough to recognize and reject
  them.  GTY'd struct/class that need to typedef their own types
  should use GTY((user)).

- Documentation on what is and is not supported.

There is one check I needed to remove that gave me some trouble.
When a ctor is detected, we have already parsed the name of the
ctor as a type, which is then registered in the list of structures.

We go on to recognize it as a ctor *after* the type has been
registered.  We reject the field in declarator() and it is never
added to the list of fields for the class.

However, when we reach the end of the class, we find that the
type we created while parsing the ctor has line number
information in it (the line where the ctor was) and gengtype
thinks that it is a duplicate structure definition.

I took out this check for two reasons: (a) It is actually
unnecessary because if there were really duplicate definitions of
this structure, the code would not compile, and (b) all the other
alternatives required making the parser much more convoluted and
I'm trying hard not to make gengtype parser too smart.
