My guess: constantPool.hpp is being changed to include allocation.hpp
rather than allocation.inline.hpp. The fanout from constantPool.hpp is
(to me) surprisingly broad: thread.hpp includes frame.hpp, which
includes method.hpp, which includes constantPool.hpp.  Nearly 70 files
directly include thread.hpp, and who knows how many additional files
indirectly include it.
