History
Nico Weber 97c675d3d4 Revert "Revert "Temporarily do not drop volatile stores before unreachable"" 
This reverts commit 52aeacfbf5.
There isn't full agreement on a path forward yet, but there is agreement that
this shouldn't land as-is.  See discussion on https://reviews.llvm.org/D105338

Also reverts unreviewed "[clang] Improve `-Wnull-dereference` diag to be more in-line with reality"
