C++ PATCH for GC

[Mark Mitchell]

Here's a fateful patch: GC is now enabled in the C++ compiler.  If you
notice C++ regressions, or bootstrap failures, please let me know.
You will notice longer compile-times.  Please bear in mind that faster
GC is coming later this week; the current version is functional, and
ultra-portable, but does not even attempt high performance.

Three cheers to Richard and Bernd for making this possible!
