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.

map on the side, Instruction no longer has to be Annotable.  This reduces
the size of the Instruction class by another 4 bytes (on a 32-bit system).

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!

This reduces the size of the instruction class by 4 bytes, and means that
isa<CallInst>(V) (for example) only needs to do one load from memory instead
of two.

This reduces the size of Instruction & Function by 4 bytes each.
