sequences in SPUDAGToDAGISel.cpp and SPU64InstrInfo.td, killing custom DAG node types as needed. - i64 mul is now a legal instruction, but emits an instruction sequence that stretches tblgen and the imagination, as well as violating laws of several small countries and most southern US states (just kidding, but looking at a function with 80+ parameters is really weird and just plain wrong.) - Update tests as needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62254 91177308-0d34-0410-b5e6-96231b3b80d8
