available when HOST_BITS_PER_WIDE_INT is not 64.
(define_insn movdi_sp64_dbl, movdi_const64_special): Likewise and
move before movdi_insn_sp64 pattern.

(define_insn sethi_di_medlow, seth44, setm44, sethh): Use
symbolic_operand as predicate for second operand.
(DImode minus split on arch32, negsi2 expander, one_cmplsi2
expander): Give set VOIDmode.
From-SVN: r21724
* reload1.c (eliminate_regs_in_insn): Handle another case when
eliminating the frame pointer to the hard frame pointer. Add
