Hi,

The following starts failing with this patch:

  opt -passes='loop-mssa(lnicm)' -o /dev/null lnicm-crash.ll

I get

  While deleting: i40 %
  Use still stuck around after Def is destroyed:  %v_299.017 = phi i40 [ <badref>, %for.body1143 ]
  opt: ../lib/IR/Value.cpp:103: llvm::Value::~Value(): Assertion `materialized_use_empty() && "Uses remain when a value is destroyed!"' failed.
