This patch separates the loop peeling utilities from Loop Unrolling to generalize it since it is no longer just being used by Loop Unrolling. (D82927 <https://reviews.llvm.org/D82927>).

This patch is a followup to D80580 <https://reviews.llvm.org/D80580>. In that patch I separate the peeling specific parameters in the UnrollingPreferences struct and form a new struct called PeelingPreferences.

This patch is also a followup to D82927 <https://reviews.llvm.org/D82927>, where loop peeling is added to loop fusion.

The diff of this patch was created assuming that D80580 <https://reviews.llvm.org/D80580> and D82927 <https://reviews.llvm.org/D82927> is merged.
