Extended Description

And another assertion in Qt series :)

Attached bytecode:

1. Produce assertion:
   llc: /home/asl/proj/llvm/src/lib/CodeGen/SelectionDAG/ScheduleDAG.cpp:367: void
   llvm::ScheduleDAG::AddOperand(llvm::MachineInstr*, llvm::SDOperand, unsigned
   int, const llvm::TargetInstrDescriptor*, std::map<llvm::SDNode*, unsigned int,
   std::lessllvm::SDNode*, std::allocator<std::pair<llvm::SDNode* const, unsigned
   int> > >&): Assertion `RegMap->getRegClass(VReg) == RC && "Register class of
   operand and regclass of use don't agree!"' failed.
   ./llc((anonymous namespace)::PrintStackTrace()+0x1f)[0x85a8cef]

   unsigned int, std::lessllvm::SDNode*, std::allocator<std::pair<llvm::SDNode*
   const, unsigned int> > >&)+0x6b9)[0x840c479]

2. Bugpoint just hangs at some step reducing it. -timeout don't work...

Lack of inline FP asm support can lead to really funny results.
