Remove the target hook TargetInstrInfo::BlockHasNoFallThrough in favor of
...
MachineBasicBlock::canFallThrough(), which is target-independent and more
thorough.

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.
