This converts the C front end.

Note that this fixes a latent bug in gcc/Makefile.in's definition of
C_TREE_H.  This is needed to avoid breaking this build with this
patch.

	* Makefile.in (C_TREE_H): Reference c/c-tree.h.

	* Make-lang.in (c/gccspec.o): Remove.
	(CFLAGS-c/gccspec.o): New variable.
	(cc1-checksum.o, C_TREE_H, c/c-aux-info.o, c/c-convert.o)
	(c/c-decl.o, c/c-errors.o, c/c-lang.o, c/c-objc-common.o)
	(c/c-parser.o, c/c-typeck.o, c/c-array-notation.o): Remove.
