tree-vect-transform.c (vectorizable_conversion): Pass the integral type to vectorize.builtin_conversion.

2008-08-08  Dorit Nuzman  <dorit@il.ibm.com>

        * tree-vect-transform.c (vectorizable_conversion): Pass the integral
        type to vectorize.builtin_conversion.
        (vectorizable_conversion): Likewise.
        * config/i386/i386.c (ix86_vectorize_builtin_conversion): Always takes
        integral type as input.
        * config/rs6000/rs6000.c (rs6000_builtin_conversion): Add case for
        FIX_TRUNC_EXPR.
        (rs6000_expand_builtin): Add case for ALTIVEC_BUILTIN_VCTUXS
        and ALTIVEC_BUILTIN_VCTSXS.
        (rs6000_builtin_mul_widen_even. rs6000_builtin_mul_widen_odd): Fix
        formatting.
