rust/tests/mir-opt/address_of.address_of_reborrow.SimplifyCfg-initial.after.mir
Nilstrieb 2beabbbf6f Rename adjustment::PointerCast and variants using it to PointerCoercion 
It makes it sound like the `ExprKind` and `Rvalue` are supposed to represent all pointer related
casts, when in reality their just used to share a some enum variants. Make it clear there these
are only coercion to make it clear why only some pointer related "casts" are in the enum.
