tree-optimization/97769 - fix assert in peeling for alignment

The following removes an assert that can not easily be adjusted to
cover the additional cases we now handle after the removal of
the same-align DRs vector.

OK, it's just an overzealeous assert that is too difficult to update for the
additional cases we now handle.  I'll remove it.

Confirmed on aarch64 with a cross, doesn't ICE on x86_64.  I can have a look.
