Actually this is a good catch. The error message is worded strangely-- it
implies that `__builtin_hlsl_and` is trying to return a struct of type `S` and
is failing because `S` can't be converted to a bool.
I will fix this by adding a check to SemaHLSL that the argument type has a bool
representation, and emitting a better error message.
