85be96354f SimplifyBuiltin: fix simplification of is_same_metatype with dynamic_self types 
Dynamic self types are not the same as non-dynamic self types.

Fixes a miscompile with dynamic self type comparisons.

bfeb2128cb remove default value for the keepUnique argument of Builder.createEndCOWMutation

MemoryLifetimeVerifier: use CalleeCache instead of AliasAnalysis

0897d8a720 MemoryLifetimeVerifier: use CalleeCache instead of AliasAnalysis 
To verify if a function may read from an indirect argument, don't use AliasAnalysis.
Instead use the CalleeCache to get the list of callees of an apply instruction.
Then use a simple call-back into the swift Function to check if a callee has any relevant memory effect set.

This avoids a dependency from SIL to the Optimizer.
It fixes a linker error when building some unit tests in debug.

fc534e1c28 SwiftCompilerSources: better APIs for handling resilient nominal types 
* add `NominalTypeDecl.isResilient`

* make the return type of `Type.getNominalFields` optional and return nil in case the nominal type is resilient.
This forces users of this API to think about what to do in case the nominal type is resilient.

let singleUse = value.uses.ignoreDebugUses.ignoreUsers(ofType: EndAccessInst.self).singleUse
```

Also, add `UseList.getSingleUser(notOfType:)`
