compiler support added for precise GC

The thing about runtime reflection is you only need it for a few classes, while 
the compiler is doomed to generate the info for all of them. Andrei suggested a 
better design, which was to use compile time reflection to generate runtime 
information, as a library routine, on an as-needed basis.

In other words, it should be a library feature, not a language feature.


I think that by making the precise GC information a library feature, not a 
compiler one, we may be reaching a tipping point where the language is powerful 
enough that we may not need to add ever more language features.
