rs6000.h (GO_IF_LEGITIMATE_ADDRESS): Use TARGET_POWERPC64 when testing LEGITIMATE_INDEXED_ADDRESS_P DFmode and DImode.

* rs6000.h (GO_IF_LEGITIMATE_ADDRESS): Use TARGET_POWERPC64
        when testing LEGITIMATE_INDEXED_ADDRESS_P DFmode and DImode.
        (LEGITIMIZE_ADDRESS): Use TARGET_POWERPC64 for INDEXED fixup.
        * rs6000.c (print_operand, case 'L'): Add UNITS_PER_WORD, not 4.
        (print_operand, cases 'O' and 'T'): Fix typos in lossage strings.
        * rs6000.md (fix_truncdfsi2_store): Remove %w from non-CONST_INT
        operand.
        (movdf_softfloat32, movdf_hardfloat64, movdf_softfloat64): Change
        'o' to 'm' for GPR variant constraints.
