OK, will do.

You can do a grep "tree-inline.h" and see that many files already depend on
tree-inline.c. As for the PLACEHOLDER machinery, given that the node is
generic, I don't think that it would be logical to move the machinery
handling it in Gigi. I don't know if privatizing the node itself is doable.
FWIW the size of cc1 on x86 grows from 54015658 to 54070225 bytes (+0.1%).
