Comment (by dfeuer):
What's it going to take to put this to bed? It sounds like comment:6
suggests there may still be something to be done despite the early inline
patch? It's not clear to me just what. For the record, this test case no
longer seems to be in the test suite, but compiling something similar
dropped from 5.5s in 7.8 to 1s in 7.10 and 8.0 to 0.8s in HEAD.
