SIL: handle drop_deinit in WalkUtils
...
Also, handle some other missing instructions in the AddressDefUseWalker, which are visited in the AddressUseDefWalker.
This enables various other optimizations, like copy elimination, in the presence of `drop_deinit`.

[SILOptimizer] Fixes the ValueDefUseWalker to handle potential unchecked_ref_cast between optional and non-optional class types.
...
The `unchecked_ref_cast` is designed to be able to cast between
`Optional<ClassType>` and `ClassType`. We need to handle these cases by
checking if the type is optional and adjust the path accordingly.

WalkUtils: handle unsafe_ref_cast which casts between AnyObject and a class
...
We need to ignore such casts because otherwise the constructed walking path wouldn't contain the right `existential` field kind.
Fixes a miscompile caused by redundant load elimination.

Allow AddressUseDefWalker to continue past MarkUninitializedInst.
...
This makes SwiftCompilerSources address/access utilities consistent with C++ and
allows them to be used in diagnostic passes.
