[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 allocation 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.
