MachineFunction: Store more specific reference to LLVMTargetMachine; NFC

MachineFunction can only be used in code using lib/CodeGen, hence we
can keep a more specific reference to LLVMTargetMachine rather than just
TargetMachine around.

Do the same for references in ScheduleDAG and RegUsageInfoCollector.
