This commit updates the existing SelectionDAG tests for the stackmap and patchpoint intrinsics and enables FastISel testing. It also splits up the tests into separate files, due to different codegen between SelectionDAG and FastISel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214382 91177308-0d34-0410-b5e6-96231b3b80d8
