Summary: It turns out HIL gets in the way of a precise heap analysis. For instance, instead of: ``` n$0 = *&x.f _ = delete(&x) *&y = n$0 ``` HIL tries hard to forget about intermediate variables and shows instead ``` _ = delete(&x) *&y = *&x.f ``` Oops, that's a use-after-delete, whereas the original code was safe. While it's easy to write SIL programs that are completely unsound for HIL, they are not generated very often from the frontends. In fact, the problem became apparent only when making the clang frontend translate C++ temporaries destructors, which produces the situation above routinely. This diff makes the minimal amount of change to make Pulse build and produce equivalent results (minus HIL bugs) starting from SIL instead of HIL. The reporting sucks for now because we need to translate SIL temporaries back into program access paths. This is done in the next diff.
