Flatten tree.h and tree-core.h

This patch flattens tree.h and tree-core.h. This work is part of the GCC 
Re-Architecture effort being led by Andrew MacLeod.

I removed the includes in tree.h and tree-core.h except for the include 
of tree-core.h in tree.h.

I modified genattrtab.c, genautomata.c, genemit.c, gengtype.c, 
gengtype.c, genoptinit.c, genoutput.c,
genpeep.c, genpreds.c, and optc-save-gen-awk to include the the 
necessary include files removed from
tree.h and tree-core.h when generating their respective files.

All other changes include the necessary include files removed from 
tree.h and tree-core.h. Note the patches modifies all the front-ends.

I bootstrapped on x86 with all languages. I also bootstrapped on all 
targets listed in contrib/config-list.mk with c and c++ enabled.

Is this okay for trunk?
