Small optimization in 'simplifyAddress'. When the offset cannot be encoded in the load/store instruction, then we need to materialize the address manually. The add instruction can encode a wider range of immediates than the load/store instructions. This change tries to fold the offset into the add instruction first before materializing the offset in a register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218031 91177308-0d34-0410-b5e6-96231b3b80d8
