DS instructions that access local memory can only uses addresses that are less than or equal to the value of M0. When M0 is uninitialized, then we experience undefined behavior. This patch also changes the behavior to emit S_WQM_B64 on pixel shaders no matter what kind of DS instruction is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201097 91177308-0d34-0410-b5e6-96231b3b80d8
