* optabs.h (OTI_flodiv, flodiv_optab): Kill.
* genopinit.c: Put floating point divide insns in sdiv_optab.
* expr.c (expand_expr): Use sdiv_optab, not flodiv_optab.
* config/gofast.h, config/c4x/c4x.h,
config/ia64/hpux_longdouble.h, config/mips/mips.h,
config/pa/long_double.h, config/rs6000/sysv4.h,
config/sparc/sparc.h: Put floating point divide libcalls in sdiv_optab.
* optabs.c (init_optab): Break into new_optab, init_optab, init_optabv.
(init_optabs): Use init_optabv for overflow-trapping optabs.
Don't init flodiv_optab. Give mov_optab, movstrict_optab, and
cmp_optab RTX codes so have_insn_for can find them.
* optabs.c (expand_simple_binop, expand_simple_unop,
have_insn_for, gen_sub3_insn): New interfaces.
* expr.h: Prototype new functions.
(enum optab_methods): Move here from optabs.h.
* builtins.c, combine.c, doloop.c, function.c, ifcvt.c,
loop.c, profile.c, simplify-rtx.c, stmt.c, unroll.c:
Use new functions instead of working directly with optabs.
* doloop.c, ifcvt.c, loop.c, profile.c, simplify-rtx.c,
unroll.c: Don't include optabs.h.
* caller-save.c, combine.c, function.c, stmt.c: Just include
insn-codes.h, not optabs.h.
* Makefile.in: Update dependencies.
* combine.c (make_compound_operation, simplify_comparison):
Fix typos testing for this or that instruction.

there, prototype in expr.h.
* gencodes.c: Cleanup: zap global variables, don't use
printf where puts will do, don't bother defining MAX_INSN_CODE
which nothing uses, let CODE_FOR_nothing get its value implicitly.
