Change WriteTypeSymbolic/WriteAsOperand to return void instead of

an ostream, which is just weird.

Rename SC_DEBUG -> ST_DEBUG

Remove static indentation strangeness from WriteConstantInt.  This makes it 
so that large structs are not broken down and printed on multiple lines.  If
there is demand for this to return, there are better ways to implement this.
