Hi Nathan,

> Can you put gcc_asserts in their place please?

I am not sure if we should add gcc_assert for things that are checked
extensively in tree_verify_flow_info.

Plus, I am thinking about dropping labels from the two arms of
COND_EXPR during the lifetime of CFG, leaving those two fields null.
Andrew MacLeod suggested to use a different tree code, but putting
null is the first step IMHO.
