PPC/s390: [Liftoff] Add histogram for bailout reasons

Port c354fb9c

Original Commit Message:

    This CL adds a new enum {LiftoffBailoutReason}, and tracks this reason
    for each bailout. This will give us data to prioritize extensions of
    Liftoff for new proposals or last missing instructions. Since we also
    track the {kSuccess} case, we will also see what percentage of
    functions can be compiled with Liftoff overall.
