* config/rs6000/rs6000.c (num_insns_constant_wide): Correct
for type promotion.
(add_operand): Get test correct for 64-bit HOST_WIDE_INT.
(non_add_cint_operand): Likewise.
(logical_operand): Likewise.
(non_logical_cint_operand): Likewise.
(print_operand): Correct printf()s for 64-bit HOST_WIDE_INT.
(print_operand_address): Correct printf() for 64-bit HOST_WIDE_INT.
(rs6000_select_rtx_section): Suppress warning.
(small_data_operand): Suppress warning.
(rs6000_got_register): Suppress warning.
* config/rs6000/rs6000.md (andsi3): HOST_WIDE_INT is a signed
type, so `J' is generally the wrong constraint for a SImode value;
use `L' instead.
(andsi3_internal2): Likewise.
(andsi3_internal3): Likewise.
(iorsi3_internal1): Likewise.
(xorsi3_internal1): Likewise.
(movsi): Likewise.
(movsf_softfloat): Likewise.
various unnamed compare insns: Likewise.
(movsi+2): Preserve sign bits of SImode constant.
(floatsidf2_internal+1): Sign-extend SImode constant correctly.
(movdf+1): Preserve high bits of DFmode constant.
(movdi_32+1): Sign-extend properly.
various unnamed compare insns: Sign-extend properly.
* unroll.c (loop_iterations): Convert HOST_WIDE_INT to unsigned
properly for mode.
* expmed.c (expand_mult_highpart): Convert HOST_WIDE_INT from unsigned
properly for mode.
(expand_divmod): Likewise.
* optabs.c (expand_fix): Keep HOST_WIDE_INT constants properly signed.
(expand_binop): Sometimes there is work to do when changing
the mode of a CONST_INT.
