Don't introduce illegal types when creating vmull operations. <rdar://11324364>

ARM BUILD_VECTORs created after type legalization cannot use i8 or i16
operands, since those types are not legal.  Instead use i32 operands, which
will be implicitly truncated by the BUILD_VECTOR to match the element type.
