 Well, maybe.
 Or maybe the rules we picked were just too conservative.

 When performing `StorageLive` on a variable that already is live, forget the value that is currently in the local variable, but otherwise keep it live.
 This is consistent with what we have caught LLVM doing.
 It is hard to get any more definite than this.

 The good news is that with this choice of MIR semantics, miri's test suite passes.
 We can thus be sure (well, insofar as the test suite is representative -- this will hopefully get better over time) that rustc produces code that follows our new rules.
