[PATCH] D107513: [MemCpyOpt/MemorySSA] Do not run the pass for prohibitively large number of memory accesses.

[Alina Sbirlea via Phabricator via llvm-commits]

This is not related to optimized uses.
The issue is when making a change in the IR, in this case inserting a memset. This triggers updating all the accesses found below that access. The renaming phase will traverse all the accesses in a block (see `MemorySSA::renameBlock`).
