2. Allow negative scales in ConvertableToGEP, so that this loop from
   alloc_tree in the Olden health benchmark is correctly raised:

       for (i = 3; i >= 0; i--)
         fval[i] = alloc_tree(level - 1, label*4 + i + 1, new);

   Stepping through the array backwards caused a negative scale.

Also use distinct names for the three types of SetMachineOperand

Rename the different versions of SetMachineOperand.

Also added a function to get a register class by ID.

Bug fix in converting-int-to-float.  Other minor stuff.

* SymbolTable::remove(Value *N) checks to see if we are internally
  inconsistent before looking for a type plane (caused a crash)
* insertEntry now does a local lookup instead of a global lookup, which was
  causing an infinite loop in the renamer logic.
* Added assertions to make sure stuff stays happy
* Now the linker correctly links the SPECINT2000 mcf benchmark
