When a live virtual register is being clobbered by an implicit def, it is spilled and the spill is its kill. However, if the local allocator has determined the register has not been modified (possible when its value was reloaded), it would not issue a restore. In that case, mark the last use of the virtual register as kill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46111 91177308-0d34-0410-b5e6-96231b3b80d8

Split the Add, Sub, and Mul instruction opcodes into separate integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately.
