If we see an "unknown operand", abort so it's easier to fix it.

Support cast of ints (and narrower) to float and double.
Support cast double to double (using load and store).
Abort if we see a CallInst or SetCondInst with long/fp args, instead
of producing bad code.
Support add, sub, mul, div of float and double.

instructions.  Instead, keep a map of instructions -> MCFI objects in the
already sparc-specific class MachineFunctionInfo.  This will slow down the
sparc backend a bit, but it does not penalize the rest of LLVM!
