* config/sparc/sparc.c (sparc_emit_set_const32): If outputting a
CONST_INT, not a symbolic reference, don't use a HIGH/LO_SUM
sequence, use SET/IOR instead so CSE can see it.
* config/sparc/sparc.md (movhi_const64_special,
movsi_const64_special): New patterns necessitated by that change.
(movhi_high): Remove.
(movhi_lo_sum): Change to match an IOR.
(movdf_insn_sp32): Test TARGET_V9 not TARGET_ARCH64.
(movdf_insn_v9only): New pattern for when V9 but not ARCH64.
(movdf_insn_sp64): Test both TARGET_V9 and TARGET_ARCH64.
(movdf splits): Allow when not V9 or when not ARCH64 and integer
registers are involved.
(snesi_zero_extend split): Remove reload_completed test.
(unnamed plus and minus zero_extend sidi splits): Add it.
