to what is needed for constant islands. The prescan method for Mips16 constant islands will eventually go away. It is only temporary and should be done earlier when the instructions are first created or from the DAG. If we keep it here we need to handle better the situation where constant islands is called multiple times since don't want to prescan more than once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195569 91177308-0d34-0410-b5e6-96231b3b80d8
