Optimize ObligationForest's NodeState handling.

This commit partially inlines two functions, `find_cycles_from_node` and
`mark_as_waiting_from`, at two call sites in order to avoid function
unnecessary function calls on hot paths.

It also fully inlines and removes `is_popped`.

These changes speeds up rustc-benchmarks/inflate-0.1.0 by about 2% when
doing debug builds with a stage1 compiler.
