        * i386.md (ahi?v*3): Set third operand type to TImode.
        * i386.c (ix86_expand_binop_builtin): Extend operand when needed.

        * simplify-rtx.c (simplify_subreg): Fix conversion from vector into
        integer mode.

        * rtl.def (VEC_MERGE, VEC_SELECT, VEC_CONCAT, VEC_DUPLICATE):
        Change code so they are arithmetic expressions now.
        * simplify-rtx.c (simplify_unary_operation, simplify_binary_operation,
        simplify_ternary_operation): Deal with VEC_* expressions.

        * i386.md (vmaskcmp, pinsrw, movd patterns):  Fix RTL representation.
