[ScopInfo] Avoid iterator invalidation.

Commit r329640 introduced the removal of all MemoryAccesses of a Scop.
It accidentally continued iterating over a vector whose iterators
have been invalidated by a MemoryAccess removal.

Make a copy of the MemoryAccesses to remove to iterate over while
removing them.
