Note that the compile time at, say, -O1 for 4.3 vs. 4.4 is also a huge
difference for the test case (4.4 much slower, in part due to the
expensive heuristic).  Therefore, IMHO, this is still a 4.4 regression
too.  We should not be running such expensive algorithms just for
inline heuristics.  We need to figure out a cheaper heuristic.
