Schedule more conservatively to account for stalls on floating point resources and latency. Use the AGU resource to model latency stalls since it's shared between FP and LD/ST instructions. This might not be completely accurate but should work well in practice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198125 91177308-0d34-0410-b5e6-96231b3b80d8
