Because about half of tree-inline.c should be in tree.c:
walk_tree(), walk_tree_without_duplicates(), copy_tree_r()
and a few others are used throughout the compiler, it is
just for historical reasons that they are in tree-inline.c

This is also why so many files include tree-inline.h while
they have nothing to do with tree inlining.

I was working on a patch for this last week but Cygwin 
bootstrap was broken.  I'll try to put something together
this week.
