AArch64: Don't call getIterator() on iterators
Remove an unnecessary round-trip:
iterator => operator->() => getIterator()
In some cases, the iterator is end(), so the dereference of operator->
is invalid (UB).
The testcase only crashes with r278974 (currently reverted to
investigate this), which adds an assertion for invalid dereferences of
ilist nodes.
Fixes PR29035.
