  Neon/AArch64: Fix/suppress UBSan warnings
  
  - Suppress a UBSan warning regarding storing a 64-bit value to a
    non-64-bit-aligned address.  That behavior is technically undefined
    per the C spec but is supported in the context of the AArch64
    architecture and compilers.
  
  - Explicitly promote block_diff[i] to unsigned int prior to left
    shifting it, in order to avoid a UBSan warning.  This warning also
    described behavior that is technically undefined per the C spec but is
    supported in the context of the AArch64 architecture and compilers.
    Changing the type cast order eliminated the warning without changing
    the generated assembly code.
  
  Closes #582
