* expr.h: Split out optab- and libfunc-related code to...
* optabs.h, libfuncs.h: ... these new headers.
* Makefile.in (CONFIG_H, EXPR_H): Take out insn-codes.h.
(OPTABS_H): New.
(various .o rules): Add $(OPTABS_H) and/or libfuncs.h to
dependencies.
* mkconfig.sh: Don't include insn-codes.h from config.h.
