[LLVMdev] [PATCH] SelectionDAG Debugging

This patch adds a couple of interfaces to dump full or partial
SelectionDAGs.  The current code only prints the top-level
SDNode.  This patch makes it much easier to understand
CannotYetSelect errors and those sorts of things.  In particular,
it helped me track down PR6019.

Any objections to committing?
