<pre>The test lvm/llvm/test:Transforms/ScalarRepl/sroa-fca.ll.test fails when
running it with -fsanitize-memory-use-after-dtor, and environment option
MSAN_OPTIONS=poison_in_dtor=1
Invalid access of member HasHungOffUses in definition of operator delete for
user. The member is inherited from llvm::Value. During test execution, the
destructor of some llvm::Value instance is invoked, and poisons its own memory.
The later destruction of the User instance fails when it attempts to access the
inherited member.</pre>
