        * rs6000.c: (altivec_expand_builtin): Only expand altivec builtins
        when TARGET_ALTIVEC.  Move handling of generic unary, binary, and
        ternary operations from here...
        (rs6000_expand_builtin): ...to here.
        New argument expandedp.
        Change all instances of altivec_expand_binop_builtin to
        rs6000_expand_binop_builtin.
        (altivec_expand_unop_builtin): Rename to
        rs6000_expand_unop_builtin.
        (altivec_expand_binop_builtin): Rename to
        rs6000_expand_binop_builtin.
        (altivec_expand_ternop_builtin): Rename to
        rs6000_expand_ternop_builtin.
