SwiftCompilerSources: improve APIs for UseList

Browse Source 
Make filter APIs for UseList chainable by adding them to Sequence where Element == Operand

For example, it allows to write:
```
let singleUse = value.uses.ignoreDebugUses.ignoreUsers(ofType: EndAccessInst.self).singleUse
```

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