Add statistics code to RTL generators

[Jan Hubicka <jh at suse dot cz>]

Hi,
currently the gen_rtx_fmt_* are output as sources of all memory
allocated by RTL.  This makes it a bit dificult to trace down where the
memory is comming from.  This patch adds necesary instrumentation
to gengenrtl.  Bootstrapped/regtested i686-linux, OK?

	* gengenrtl.c (gendecl, gendef): Output the gens annotated for
	statistics.
	(genheader): Include statistics.h.
