CodeGen: Stop using LeakDetector for MachineInstr
Since `MachineInstr` is required to have a trivial destructor, it cannot
remove itself from `LeakDetection`. Remove the calls.
As it happens, this requirement is because `MachineFunction` allocates
all `MachineInstr`s in a custom allocator; when the `MachineFunction` is
destroyed they're dropped of the edge. There's no benefit to detecting
leaks.
