utils.c: Do not include function.h, pointer-set.h, and gimple.h.

	* gcc-interface/utils.c: Do not include function.h, pointer-set.h,
	and gimple.h.  Explain why rtl.h has to be included.
	(handle_vector_size_attribute): Call reconstruct_complex_type directly.
	* gcc-interface/targtyps.c: Do not include tm_p.h
	* gcc-interface/utils2.c: Do not include flags.h.
	* gcc-interface/trans.c: Do not include expr.h.  Include rtl.h instead,
	and explain why it has to be included.
	* gcc-interface/misc.c: Do not include expr.h, libfuncs.h, cgraph.h,
	and optabs.h.
	Include function.h and explain why.  Explain why except.h is included.
	(enumerate_modes): Remove unused function. 
	* gcc-interface/gigi.h (enumerate_modes): Remove prototype.
	* gcc-interface/Make-lang.in: Update dependencies.
