Move SlotCalculator.h to lib/Bytecode/Writer since that is the only place

that needs it after the Type != Value changes (bug 122).

-// This class calculates the slots that values will land in.  This is useful for
-// when writing bytecode or assembly out, because you have to know these things.
-//
-// Specifically, this class calculates the "type plane numbering" that you see
-// for a function if you strip out all of the symbols in it.  For assembly
-// writing, this is used when a symbol does not have a name.  For bytecode
-// writing, this is always used, and the symbol table is added on later.
