All the infrastructure for functions as trees is at present
C/C++-specific.  The names of tree-dump.* and tree-inline.* are
misleading, since these files too are C/C++ specific and include C front
end headers.

The basic infrastructure should be changed not to be C/C++ specific; the
tree codes, except those that arguably are C/C++ specific rather than
generic, should become generic ones, and the tree-* files should stop
including C/C++ headers, instead using language hooks to handle those tree
codes that are specific to C/C++.  All the necessary infrastructure
functions presently in the C/C++ files, to handle those tree codes that
become generic, should move to the generic files.

Non-C-family front ends should not use c-common.c.
