title: Loading in 256bit vector register in AVX2 Haswell processor
body: <p>I want to load a <code>256 bit YMM</code> register with 32 values, each of length 1 byte.  All the intrinsic I looked into load either <code>double word</code>, i.e., <code>4 byte</code> integers or <code>quad word</code>, i.e., <code>8 byte</code> values.
  How to load data of size lesser than these?
  Is there any mnemonic which does this but don't has a equivalent intrinsic?</p>
