Replace TargetInstrInfo::isInvariantLoad and its target-specific
implementations with a new MachineInstr::isInvariantLoad, which uses MachineMemOperands and is target-independent. This brings MachineLICM and other functionality to targets which previously lacked an isInvariantLoad implementation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83475 91177308-0d34-0410-b5e6-96231b3b80d8
