        * config/i386/i386-builtin-types.def
        (VOID_FTYPE_PDOUBLE_QI_V8SI_V4DF_INT,
        VOID_FTYPE_PFLOAT_QI_V4DI_V8SF_INT,

        VOID_FTYPE_PLONGLONG_QI_V4SI_V2DI_INT,
        VOID_FTYPE_PINT_QI_V2DI_V4SI_INT): New builtin types.
        * config/i386/i386.c (enum ix86_builtins): Add
        IX86_BUILTIN_SCATTERALTSIV4DF, IX86_BUILTIN_SCATTERALTDIV8SF,
        IX86_BUILTIN_SCATTERALTSIV4DI, IX86_BUILTIN_SCATTERALTDIV8SI,
        IX86_BUILTIN_SCATTERALTSIV2DF, IX86_BUILTIN_SCATTERALTDIV4SF,
        IX86_BUILTIN_SCATTERALTSIV2DI and IX86_BUILTIN_SCATTERALTDIV4SI.
        (ix86_init_mmx_sse_builtins): Fix up names of IX86_BUILTIN_GATHERALT*,
        IX86_BUILTIN_GATHER3ALT* and IX86_BUILTIN_SCATTERALT* builtins to
        match the IX86_BUILTIN codes.  Build    IX86_BUILTIN_SCATTERALTSIV4DF,
        IX86_BUILTIN_SCATTERALTDIV8SF, IX86_BUILTIN_SCATTERALTSIV4DI,
        IX86_BUILTIN_SCATTERALTDIV8SI, IX86_BUILTIN_SCATTERALTSIV2DF,
        IX86_BUILTIN_SCATTERALTDIV4SF, IX86_BUILTIN_SCATTERALTSIV2DI and
        IX86_BUILTIN_SCATTERALTDIV4SI decls.
        (ix86_vectorize_builtin_scatter): Expand those new builtins.
