This enables use of MemorySSA instead of MemDep in MemCpyOpt. To allow this without significant compile-time impact, the MemCpyOpt pass is moved directly before DSE (in the cases where this was not already the case), which allows us to reuse the existing MemorySSA analysis. Unlike the MemDep-based implementation, the MemorySSA-based MemCpyOpt can also perform simple optimizations across basic blocks. Differential Revision: https://reviews.llvm.org/D94376
