[MemorySSA] A question about how to update the MemorySSA when we call RecursivelyDeleteTriviallyDeadInstructions
When we erase a memory access instruction, existing passes using
memory ssa like GVN, NewGVN, GVNHoist and EarlyCSE uses
MemorySSAUpdater to do the update before the instruction is erased.
However, if we call llvm::RecursivelyDeleteTriviallyDeadInstructions
to find out dead instruction recursively and memory access
instructions may be erased inside the recursive process, we need a way
to update
