[M68k] fix -Wdefaulted-function-deleted and -Woverloaded-virtual

Fixes the following warnings observerd when building the experimental
m68k backend (-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD="M68k"):

../lib/Target/M68k/M68kMachineFunction.h:71:3: warning: explicitly
defaulted default constructor is implicitly deleted
[-Wdefaulted-function-deleted]
  M68kMachineFunctionInfo() = default;
  ^
../lib/Target/M68k/M68kMachineFunction.h:24:20: note: default
constructor of 'M68kMachineFunctionInfo' is implicitly deleted because
field 'MF' of reference type 'llvm::MachineFunction &' would not be
initialized
  MachineFunction &MF;
                   ^
