zero_constant just matches CONST0_RTX(V8HImode), so if for some reason
whomever created the 0 const_vector did not use const_tiny_rtx[0][V8HImode]
for the zero constant, the pattern won't match.
Who is responsible for using const_tiny_rtx, gen_rtx_CONST_VECTOR,
or the caller of gen_rtx_CONST_VECTOR ?
