 	* gensupport.c: Define get_insn_name and record_insn_name here.
 	(read_md_rtx): Call record_insn_name as appropriate.
 	* genattr.c, genattrtab.c, gencodes.c, genconfig.c, genemit.c
 	* genextract.c, genflags.c, genopinit.c, genoutput.c, genpeep.c
 	* genpreds.c, genrecog.c: Don't define get_insn_name nor
 	record_insn_name.
 	* Makefile.in (BUILD_SUPPORT, BUILD_PRINT): Fold into BUILD_RTL.
 	(BUILD_VARRAY): Delete.
 	(genprognormal): Rename genprogmd.  Fold in all programs from
 	genprognoprint; also attrtab.
 	(build/genattrtab): Just mention genautomata.o and varray.o.
 	Reorganize a bit, add comments to make the categories clearer.
