ca5e4f8e19 reenable r101565, removing a problematic assertion.
CGSCC can delete nodes in regions of the callgraph that
have already been visited.  If new CG nodes are allocated
to the same pointer, we shouldn't abort, just handle it
correctly by assigning a new number.  This should restore
stability by removing invalidated pointers that *will* be
reused from the densemap in the iterator.

bde0bb5f88 building on the new CallGraphSCC abstraction, teach CallGraphSCCPassManager
to keep the node entries in scc_iterator up to date instead of dangling as
the SCC mutates.

This is a really terrible problem which was causing -g to affect codegen 
because it would permute the memory image of the compiler process.

Thanks to Dale for expertly hunting it down.

4a20c7a0a9 1. Allow SCCIterator to work with GraphT types that are constant.
2.  Allow SCCIterator to work with inverse graphs.
3.  Fix an incorrect comment in GraphTraits.h (the type in the comment 
was given as GraphType* when it is actually const GraphType &).
Patch by Patrick Alexander Simmons.
