    [965] Replace various alignment code with a shared ALIGN() macro.
    
    In the process, fix some alignment issues:
    - Scratch space allocation was aligned into units of 1KB, while the allocati
      wanted units of bytes, so we never allocated enough space for scratch.
    - GRF register count was programmed as ALIGN(val - 1, 16) / 16 instead of
      ALIGN(val, 16) / 16 - 1, which overcounted for val != 16n+1.
