Classes need to have a prefix name, so that they can be tacked on to the pieces
that TableGen creates for them, e.g. CodeEmitter, AsmPrinter, etc.

This is the initial draft of the Compiler Driver documentation. It is not
worthy of review at this point. There is much thought and content remaining
to be written.
