vect: Don't guard scalar epilogue for inverted loops [PR118211]

For loops with LOOP_VINFO_EARLY_BREAKS_VECT_PEELED we should always
enter the scalar epilogue, so avoid emitting a guard on entry to the
epilogue.

gcc/ChangeLog:

PR tree-optimization/118211
PR tree-optimization/116126
* tree-vect-loop-manip.cc (vect_do_peeling): Avoid emitting an
epilogue guard for inverted early-exit loops.
