[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.
