* tree-vect-stmts.c (vect_build_gather_load_calls): For NARROWING
and mask with integral masktype, don't try to permute mask vectors,
instead emit VEC_UNPACK_{LO,HI}_EXPR.  Fix up NOP_EXPR operand.
(vectorizable_store): Handle masked scatters with decl and integral
mask type.
(permute_vec_elements): Allow scalar_dest to be NULL.
* config/i386/i386.c (ix86_get_builtin)
: Use lowpart_subreg for masks.
: Don't assume mask and src have
to be the same.
