[committed] Fix build/min-insn-modes.o rule

[committed] Fix build/min-insn-modes.o rule

[Richard Sandiford]

Jeff pointed out privately that r249881 left build/min-insn-modes.o
with no dependence on insn-modes.h, which could cause a build failure
in highly-parallel builds.  Fixed with the patch below.  I also cleaned
up some uses of machmode.h and double-int.h that have been out-of-date
for a while; these are now always included via coretypes.h.

Tested on x86_64-linux-gnu with "make -j" and applied as obvious.

Sorry for the breakage.

Richard

gcc/
	* Makefile.in (HOOKS_H, RTL_BASE_H, FUNCTION_H, EXPR_H, REGS_H)
	(REAL_H): Remove $(MACHMODE_H).
	(FIXED_VALUE_H, TREE_CORE_H, CFGLOOP_H): Remove $(MACHMODE_H) and
	double-int.h.
	(CORETYPES_H): Add signop.h, wide-int.h, wide-int-print.h,
	$(MACHMODE_H) and double-int.h.
	(build/min-insn-modes.o): Depend on $(CORETYPES_H) rather than
	$(MACHMODE_H).
	(gengtype-state.o, gengtype.o, build/gengtype.o): Don't depend on
	double-int.h.
