* Makefile.in (HOST_CFLAGS): Take out -DGENERATOR_FILE.

	 (CONFIG_H, TCONFIG_H, TM_P_H): Update.
	 (GEN, STAGESTUFF): Add new files.
	 (insn-constants.h, s-constants, tm-preds.h, s-preds,
	 genconstants, genpreds, genconstants.o, genpreds.o): New rules.
	 (hashtab.o, safe-ctype.o): Add -DGENERATOR_FILE.
	 * mkconfig.sh: Include tm-preds.h in tm_p.h; insn-constants.h
	 as well as insn-codes.h and insn-flags.h in config.h; and no
	 extra headers in tconfig.h and hconfig.h.

	 * gencodes.c: Eliminate code to generate predicate declarations
	 or #defines for md-file constants.
	 * genconstants.c, genpreds.c: New files.

	 * i386.md: Re-order guard expressions such that TARGET_64BIT
	 comes first, when this permits better optimization.  Add
	 TARGET_64BIT to more x86-64 patterns.  Add comment explaining
	 why this is desirable.
