Whether there's anything to do for the cleanup path, that is, when unwinding through this scope. This includes destructors, but not StorageDead statements, which don't get emitted at all for unwinding, for several reasons:

set of places to drop when exiting this scope. This starts out empty but grows as variables are declared during the building process. This is a stack, so we always drop from the end of the vector (top of the stack) first.

Invalidate all the cached blocks in the scope.

Should always be run for all inner scopes when a drop is pushed into some scope enclosing a larger extent of code.

storage_only controls whether to invalidate only drop paths run StorageDead. this_scope_only controls whether to invalidate only drop paths that refer to the current top-of-scope (as opposed to dependent scopes).
