This was hardcoded to the static private size, but this would be missing the offset and additional size for someday when we have dynamic sizing. Also stops always initializing flat_scratch even when unused. In the future we should stop emitting this unless flat instructions are used to access private memory. For example this will initialize it almost always on VI because flat is used for global access. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@260658 91177308-0d34-0410-b5e6-96231b3b80d8
