- Remove code which lowers pseudo SETGP01. - Fix LowerSETGP01. The first two of the three instructions that are emitted to initialize the global pointer register now use register $2. - Stop emitting .cpload directive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156689 91177308-0d34-0410-b5e6-96231b3b80d8
