1. Remove the LLVM_DO_NOT_BUILD feature (not needed any more)

When we legalize target nodes, do not use getNode to create a new node,

use UpdateNodeOperands to just update the operands! This is important because
getNode will allocate a new node if the node returns a flag and this breaks
assumptions in the legalizer that you can legalize some things multiple times
and get exactly the same results.
