Can't compile selection sets with multiple items on Xcode 11.4

Currently, the selection sets that include multiple Add selections does not compile without explicitly declaring all type information. This seems to be related to internal changes to @_functionBuilder.

Fixed by using a development snapshot version of Swift off its master branch and updating to use the buildExpression feature of function builders to map Add instances to SelectionSet instances.
