This patch switches the return type in `MemorySpaceAttrInterface` methods from `LogicalResult` to `bool`. As `is*` methods are predicates. Users of the `MemorySpaceAttrInterface` API must note that, if `emitError` is non-null and the result of a `is*` method is `false`, then an error was likely emitted. To avoid the emission of an error the user can pass a default constructed `emitError`.
