9084bb5471 rewrite Value::takeName to take advantage of the new symtab stuff. This 
causes it to require no allocations and no symtab lookups in the common
case.  This speeds up instcombine 9.2% on 447.dealII.

5d0b16f797 Implement Function::getIntrinsicID without it needing to call Value::getName,
