Log:
  Merge commit 8e34dd941 from llvm git (by Sanjay Patel):

    [x86] avoid crashing when splitting AVX stores with non-simple type
    (PR43916)

    The store splitting transform was assuming a simple type (MVT), but
    that's not necessarily the case as shown in the test.

  This should fix 'Assertion failed: (isSimple() && "Expected a
  SimpleValueType!")' when building the security/openssl111 port targeting
  a CPU that supports AVX, but not AVX2, such as sandybridge.
