When GlobalISel is configured to abort rather than fallback the only
thing that resetting the machine function does is make things harder
to debug. If we ever get to this point in the abort configuration it
indicates that we've already hit a bug, so this changes the behaviour
to abort instead.

As the development of GlobalISel move forward, this statistic should
strictly decrease until it reaches zero. At this point, it would mean
GlobalISel can replace SDISel (at least on the tested inputs :P).

When global-isel fails on a MachineFunction MF, MF will be cleaned up
and given to SDISel.
Thanks to this fallback, we can already perform correctness test even if
we support only a small portion of the functions in a test.
